Vayama review: Needing my flight refund from flight being canceled by airline during pandemic

I bought a ticket in December 2019 for Bucharest, Romania with the Condor Airline. My flight was canceled by the airline on June 19th, 2020 (when the flight should have taken place) and when I called them they said they will be refunding me the money in 2 to 3 weeks. The money didn't come and when I called again and I gave them the last 4 digits of my credit card they said that was not the credit card the money was put back on. I realized then that Vayama agency's credit card was refunded and every time I email Vayama to ask for my refund (there is not customer service, no phone number), I am told again and again that I need to get in touch with the airline and deal with them directly. I am a student and would like to use my refund for school. Obviously Vayama is wanting to keep the money - that is absolutely unacceptable and it is called theft.
