Complaint Review: Aspire

In 2004-2005 my husband and I had an offer made to us to settle our account with Aspire for our credit card. We did so. Now, all these years later, they are garneshing my husbands wages for almost $4000.00 when we settled for less than half of that amount.
This has taken place when Aspire and Providian sold acounts to each other, they issued us another account number and that now we have to prove that the 2 accounts numbers are for the same account. I have my bank statement showing that I paid the amount, but how can I prove that the 2 account numbers are 1 in the same?
It seems to me that this company is running a really good scam.
