Hi Leslie,
I really feel for you at this time and think that you should have done some research before sending money to Ellis Crosby.
This company was trying to scam people beyond imagination some months back. Now that the company has filed for bankruptcy, but still they are using other names for doing their business. But the tactics of collection still remains the same, it's illegal.
You say that you don't have any receipts to prove your payment. This could have been a very strong proof if any other CA contacts you for the same debt some time later. Now, that you don't have anything to prove for what you have been with, you might have to start from the beginning.
But you should file your complaints to the consumer protection office as well as the FTC and the BBB. Request them to go through your complaint because people are getting scammed by companies day after day.
Regards
Roxette
