Pegasus Denied Me Boarding After eDreams Issued an Invalid Reservation

I booked a round-trip flight ticket with Pegasus Airlines through eDreams, the payment was processed on my card, and I was issued an itinerary with reference number 2alwf5. Despite this, when I arrived at the Pegasus counter at the airport today, I discovered that my reservation was not in their system and I was denied boarding.

Pegasus staff claimed the issue was caused by eDreams and told me I needed to contact them directly. However, I cannot reach eDreams through any support channel, leaving me unable to use my ticket and without any resolution regarding the money I paid.

I demand that this paid reservation—for which I received a reference code—either be honored in full for flight credit or that the entire charge be refunded to my credit card immediately. I request an urgent resolution to this issue and a formal response in writing.
