Debt Busters after sales service and customer service leaves much to be desired

I signed up with Debt Busters several years ago. The after sales support has been very poor. You have to deal with a call centre and can never get hold of the same person you spoke to previously. It is very frustrating dealing with Debt Busters. My Debt Repayment timelines have increased substantially since I signed up and I have yet to receive a proper and comprehensive response as to the issue I have queried, which involved the Banks charging monthly bank charges / service fees on the accounts which absorbed the bulk of the debt repayment amounts, and resulted in a much lower amount being paid towards my debt. This resulted in my debt repayment being taken over a much longer period than I was originally quoted. I am strongly considering changing Debt Counsellors.
