I first sent Asset Acceptance a letter in order for them to verify the debt owed and they responded, however the account was past the SOL. 

Since their response, We had agreed to settle the debt in exchange that they will remove the following account from my credit report. However they have not complied with the agreement, and the account remains open and reported as unpaid. I have paid them, and they are saying that it will take __ amount of days to receive a receipt.
