CheapOair review: Ticket refund to include extra fees charged

On June 3, 2019 I scheduled a flight from Las Vegas, NV to Vienna on Condor Air through Cheap-O-Air. When I couldn't find a return flight site I contacted them for help in scheduling a return flight. This was a direct flight, round trip, economy class. I was on the phone with their scheduling office for over an hour and a half and at the end of the call I had a return flight ticket, which cost me much moe than my one ticket cost plus hidden fees and overcharges which I had never heard of. Today, June 28 2019, I called to cancel my flight on July 3, 2019 because of a medical situation that prevented me and my wife from flying at this time and I requested to reschedule for the next month (August 2019). They politely informed me that this action would cost an additional fee of $599.00 per person just because I cancelled. This would put my total cost to increase by almost $1, 000.00 and at this time I refused and hung up. I feel that Cheap-o-Air overcharged me in the first place for a flight that should have only cost around $3, 400.00 versus the $4, 306.00+ ticket fees charged. My Booking is #[protected]. I feel that this company operates on hidden fees, overchrged tickets and undisclosed fees and information and if no refund is not forthcoming, rest assurred that I will take this matter all the way to the highest court and every media source I can find to put information out to the public of how this company operates. This is a corrupt travel agency and people should be aware of their practices.
