Midland Credit Management and I agreed to pay {$760.00} for a XXXX XXXX debt. 

Midland prints checks to present to my bank for the payment. 

My bank notified Midland that their check was not being printed correctly. After XXXX payments and no response or change from Midland, my bank refused to accept their check. 

I contacted Midland and they reinstated the payment plan and corrected their check account number. Midland did not inform me that they were no longer agreeing to the original agreed upon debt amount. After making the final payment, Midland wants to collect {$480.00} more in debt payments.
