False statements or representation: Debt collection

The amount on the statement is incorrect. This account has been sold to 2 different companies with the incorrect amount. It has been placed on my credit report with the wrong amount and I have been fixing dealing with this issue of the amount is incorrect. I have disputed the amount with credit bureaus and to no have not been successful. I have the statement that shows the correct amount but the collection agencies are being very unprofessional and not willing to correct the information.
