1. I bought a reservation from you
2. I tried to cancel but you denied the request
3. AT suggested I resell it
4. I sold it to someone else
5. They went to the restaurant and said their reservation was cancelled
6. You cancelled it - SO YOU KEPT THE MONEY FROM THE SALE AND CANCELLED THE RESERVATION SO NOW I LOST OUT ON MONEY

I will seek legal council to make sure I get the money back from you.
