***** and dishonest business with the worst service ever!!

They have de*****ed my husband for 4 years and now he is being called by lawyers demanding him to pay accounts which were supposedly being paid all those years as per the NDC's claim,only to learn that they never paid a single cent...how do I even take legal steps against these people??? He trusted them with assisting him get out of debt through paying reduced installments,only to find they were de*****ing him.
