CheapoAir will not give me refund

In September, I was to go on a trip, but do to circumstances had to postpone the trip. I called CheapoAir twice before deciding what to do. I was told that my options were: 1) Find tickets at a later date and would be charged $200 per ticket OR 2) Get a refund for the tickets, but be charged a cancelation fee of $150 per ticket.
Because I could not get a ticket for the date I wanted (to far in advance for cheapoair to reserve), I chose to get a refund. I should have lost $450 (3 tickets) out of the $1640.99, receiving 1190.99. I have received a total of $534.60 (meaning they should owe me $656.39).
I am still owed over $600 and have spoken with cheapoair at least 8 times on the matter. Most of the individuals I have spoken to could not help me and told me they could not get help from a supervisor. I am told that customers can not talk to the refund department directly, after they have dealt with a case (hmm...now I know why!). Finally today I was told that the airline company they (cheapoair) buys tickets from also charges a fee for cancelation, which was $400. I was NEVER told this when dealing with Cheapoair in September when canceling my flight. I again asked to speak with the refund department, as this is who I dealt with before and they never told me about the airline fee. The woman I spoke with, basically said that she can not do anything about the misunderstanding except to explain it to me now. I stated, "So after the fact, you clearly explain this to me? I should have been given the facts in September"
I am feeling quite frustrated at this point and wondering if there is anything I can do.
What can I do legally? Can I take action, or am I just screwed?
Can I take them to small claims court?

I have received one e-mail from you, Renee. I replied to you and have not heard back from you or a supervisor since. From what I have researched, it seems that Cheapoair has a hard time giving people back refunds.
My meeting with a lawyer is not far away.

Sincerely,
B. Bakken

Brittney, I will check with the billing department manager, I had sent your email over to her to contact you. Refunds are not determined by me, but the concerned department.

Our billing department had to leave a voice mail for this customer, all refunds have been processed and explained how they had been dispursed. This case has been resolved.

This case as not yet been resolved. Cheapoair keeps you on the line for hours and still gives no answers.

Brittney, I show that our billing department contacted you and had to leave a voice mail. I don't understand why other refunds you are requesting. Please provide me with the booking confirmation once again.
