Pegasus Refund Not Received – No Resolution For Over 2 Months

I am writing to express my deep dissatisfaction with Pegasus Airlines regarding a refund of €209, which I have been waiting for over two months without resolution. I purchased a ticket through Pegasus using Trustly (via Girogate) as the payment method. I later cancelled the ticket, and Pegasus claimed the refund was processed on 11 May 2025 (PNR: CA6WYF). Instead of sending the refund directly to my account, Pegasus claimed they sent it to Trustly, the intermediary payment provider I used via Girogate. I contacted Trustly, and they confirmed that they attempted to send the refund to my bank, but the transaction was rejected. Trustly then returned the money to Pegasus via PPRO, their payment partner, so the money never reached me. Trustly has also stated that Pegasus is not responding to their attempts to follow up. Despite providing Pegasus with all transaction details, they continue to insist the refund was successful and suggest I "contact my bank," which makes no sense, as the money was returned to Pegasus. The Pegasus Guest Relations team has confirmed to me that they are aware of issues with this payment method. If that is the case, why is this payment method still available on their website? And more importantly, why have they not refunded my money directly to me? I have contacted Pegasus customer service multiple times with no useful outcome. Reached out to Trustly, who have requested Pegasus follow up. Contacted my bank, which confirmed no transaction was received or rejected. I am now stuck between Pegasus and Trustly, both avoiding responsibility while my money remains unreturned. I request that Pegasus: Investigate the refund internally with their payment provider (PPRO), provide proof of refund or confirm receipt of the returned funds from Trustly, issue the refund directly to my account without further delay. If this issue is not resolved promptly, I will escalate the matter to the Turkish Civil Aviation Authority (SHGM) and the European Consumer Centre (ECC). This has been extremely frustrating and unprofessional. I expect a timely and proper resolution.
