Wizz Air Customer Service Refused Refund Without QR Code Proof

On September 16, I purchased a ticket from Wizz Air for flight W62430, scheduled from Istanbul to Budapest. However, due to overbooking, I was denied boarding and had to buy a ticket from another airline at the last minute. At that time, I was informed that Wizz Air would reimburse me for the cost of the new ticket.

I submitted a refund request and provided all the required documents. The QR-coded portion of my boarding pass was taken by the airline staff at boarding, so I only have the baggage and boarding copy in my possession. Despite explaining this, customer service keeps insisting on receiving the QR-coded section. The ticketing staff confirmed that the boarding document can only be printed once and cannot be reissued.

It has now been about five days, and I am still waiting for a resolution. Customer service has not initiated the refund process, nor addressed my issue. I paid ₺15,000 for the new ticket from another airline and demand a full refund of this amount.

I expect Wizz Air to honor its commitment and reimburse the full ticket cost as promised.
