Cheapoair Fareportal, Inc. They cancelled my booking and stole my money! New York New York

On March 15, 2015, I purchased four round trip airline tickets for a total of $2,268.84.  On June 23, 2015, I called to inquire about a refund and was advised that a waiver would be sent requesting a refund, but was not guaranteed.  I was simply inquiring about a refund and at no point authorized a cancellation of the booking.  I was told I would receive an answer in 15 days.  The 15 days passed with no contact so I called again on July 6, July 14, July 20, July 23, July 29, and August 10.  Each time I was given a different excuse as to why t was taking such a long time for a response.  At one point, the customer service representative told me it was taking a long time because it was a lot of money involved.  I contacted the airline and was advised that Cheapoair is a travel agent and that the airline has nothing to do with the tickets since Cheapoair owns the tickets.  Furthermore, I found out on August 10 from the airline that Cheapoair cancelled my booking on June 23, which was the very first call I made to them.  For almost two months, Cheapoair has lied to me by telling me that my booking was still in place and it even shows as an upcoming trip on their website.  According to the airline, my four tickets have already been sold to someone else and the flight is now unavailable.  I called Cheapoair and asked to speak to a supervisor.  The person was argumentative and was caught in several lies during the call.  The “supervisor” refused to help and said he could only book another flight to include charging me an additional $800 plus any difference in the airfare.  My original flight is no longer available and all he can do is cite a “no guarantee” policy.  The no guarantee is for the refund.  I did not expect Cheapoair to cancel my booking, sell my four tickets, and keep the $2,268.84.  This seems like larceny to me.
