Include the date or dates attended, approximate arrival and queue times, the sessions or areas you could not access, the guidance provided by staff, and the resulting impact on your attendance. Explain what you were and were not able to access. Mention physical discomfort or other consequences only if you experienced them.]****[OPTIONAL — retain only if accurate: Following your email of 22 September, I returned on 23 September in good faith, relying on your assurances that access and queue management would improve. Nevertheless, the following problems persisted: DESCRIBE WHAT HAPPENED.]**The evidence supporting my complaint includes **[LIST THE EVIDENCE YOU ACTUALLY HAVE: RECEIPT, PHOTOGRAPHS, VIDEOS, CORRESPONDENCE, TIMESTAMPS OR OTHER RECORDS]**.## Foreseeable planning and access failuresIn your co-founder’s email of 22 September, the organisation acknowledged long entry queues, capacity restrictions and attendees missing sessions, while describing a community of approximately 10,000 people.**[OPTIONAL — include this paragraph only with the supporting capacity analysis and source material: A provisional reconstruction using WTC Barcelona’s published room capacities and the identified session spaces estimates approximately 1,150–1,220 simultaneous session seats, depending on configuration and confirmation of the smaller-room allocation. The analysis also identifies a higher total of approximately 1,750 seats in the organiser’s published figures. This discrepancy requires clarification. These figures concern session seating, not legally authorised venue occupancy, and do not establish how many people were present simultaneously.]****[OPTIONAL — retain only with supporting evidence: In-person tickets continued to be publicly offered after the event had already started, despite the access and capacity problems being experienced by attendees. The supporting evidence is attached.]**Taken together with the problems described above, these circumstances raise serious concerns about a **foreseeable failure to align expected attendance, usable session capacity, continued ticket availability and admission arrangements**.Assessing those factors and implementing an effective access plan were fundamental advance-planning responsibilities. The growth of the event does not adequately explain why attendees were left unable to make meaningful use of the service purchased.My complaint concerns substantial failures in the delivery of the in-person event, rather than dissatisfaction with one particular session or a change of mind about attending.## Refund and applicable contractual termsI consider the failures described above to constitute substantial contractual non-performance.Accordingly, I seek **termination of the contract under Article 1124 of the Spanish Civil Code and repayment of the full ticket price**, reserving the purchaser’s rights under Article 1101.The standard of diligence under Article 1104 is also relevant to the planning and access-management failures described above.Spanish Civil Code: https://www.boe.es/buscar/act.php?id=BOE-A-1889-4763If you rely on contractual restrictions to reject this request, please provide the complete version of the Terms & Conditions incorporated into the purchase on **[PURCHASE DATE]**, together with evidence of their acceptance.If you contend that subsequent amendments apply to this purchase, please identify:- the amendments;- their effective dates;- the contractual basis upon which they are said to apply to an already completed purchase; and- evidence that those amendments were validly incorporated into the contract.A link to a currently editable webpage does not, by itself, establish which terms were accepted for this order.**I do not accept recordings, vouchers, credit or a pass for a future edition as a substitute for reimbursement or as settlement of this complaint.**Please confirm approval of the **100% refund in writing within 24 hours of receipt**.Please process the refund without delay, and no later than **seven calendar days after receipt of this email**, through the original payment method and without deductions.Please also provide the refund transaction confirmation and any corresponding credit invoice.If you reject this request, please provide a substantive written response addressing:1. the specific failures described above;2. the factual grounds for refusing reimbursement;3. the contractual provisions relied upon;4. the version of the Terms & Conditions applicable on the date of purchase; and5. evidence that those terms were incorporated into the contract.A generic reference to a non-refundable ticket policy or individual session capacity does not address the substance of this complaint.Please preserve all records relevant to this matter, including:- ticket sales records;- attendance and admission records;- room and venue capacity planning;- queue and access-management records;- ticket availability and sales during the event;- internal operational records concerning the problems experienced on 22 and 23 September;- the versions of the Terms & Conditions applicable at each relevant date; and- records evidencing acceptance of those contractual terms.I remain available to resolve this matter directly in writing.Failing a satisfactory resolution, I reserve the right to pursue available payment-dispute and legal remedies, including coordinated action with other affected purchasers.The present monetary demand is limited to the ticket price, without waiver of any other applicable rights or separately recoverable losses.---**Purchaser:** [FULL NAME OR COMPANY NAME] **Company VAT number:** [IF APPLICABLE — OTHERWISE DELETE] **Attendee name(s):** [NAME(S)] **Ticket type and quantity:** [DETAILS] **Total refund requested:** €[AMOUNT], including VAT **Purchase date:** [DATE] **Order reference:** [REFERENCE] **Invoice number:** [IF AVAILABLE — OTHERWISE DELETE] **Ticket ID(s):** [IF AVAILABLE — OTHERWISE DELETE] **Booking email address:** [EMAIL]Yours sincerely,**[FULL NAME]** [ROLE AND COMPANY, IF ACTING ON BEHALF OF THE PURCHASER]### Attachments- [INVOICE / RECEIPT]- [PHOTOS]- [VIDEOS OR VIDEO LINK]- [SCREENSHOTS]- [RELEVANT EMAILS]- [OTHER EVIDENCE]---## Supporting note — session capacityThe approximately **1,150–1,220 simultaneous-seat estimate** is a provisional reconstruction based on published WTC Barcelona room capacities and the spaces identified by AI Summit Barcelona.It is an estimate of the number of seats available for simultaneously attending programmed sessions.It is **not a claim about the legally authorised occupancy of the entire World Trade Center Barcelona**, nor does it establish how many attendees were physically present at any particular moment.People using this paragraph should retain the calculation, assumptions and source material supporting it.WTC Barcelona spaces: https://wtcbarcelonaevents.com/espacios/AI Summit Barcelona stages: https://aisummitbarcelona.com/stagesSimilarly, any statement that tickets remained available after the event started should only be retained if the sender has a dated screenshot or other supporting evidence.---## Important note for users of this templateThis is a shared complaint template, not individual legal advice.Each sender should ensure that:- the facts accurately describe their own experience;- they only claim losses or difficulties they personally experienced;- any evidence mentioned actually exists;- the purchaser information matches the invoice or receipt; and- optional paragraphs unsupported by their own evidence are removed.
