I 've been paying on debt with ASSET ACCEPTANCE , LLC and after several attempts i was unable to contact them and left several messages, i was also with a credit counciling : FAMILY Credit Management and they were unable to get in touch with them after several attempts, anyways we did finally contact them but them amount owed had changed several times and during payments i had them down to {$1400.00} and change when they informed family credit management that i was being charged with a 4 % interest and had no prior written agreement or acknowledgement, i finally paid them off this last week XXXX XXXX, 2015 or so through family credit management, when i asked family credit management for a detailed payment history to them the original balance was {$2500.00} and they told me it was {$2700.00} when i added up the payment history i received through family credit management it totaled more than {$3600.00} and i mentioned this to them and they blew me off. i would like to get some of money back and an explanation why i was told about the interest rate of 4 % on an old cell phone bill, too which I 'm still with the company.
