Furious

I have heard the worst experience with the dpp account. they failed to debit my account for the past 16 months via debit order as per the contract I signed with them. our final agreement was that I pay manually of which I have done till today. I have been paying on the 26th of each month manually, and now for the past 3 months all of a sudden their debit order system decides to work. and I have been receiving debit orders that I could not understand and reversed them as I knew I had paid manually. Now I get a message that I owe almost r4000 because I reversed the debit order and my account has been disconnected. I called the call centre and the lady said I reversed the debit order, I said to her yes, and asked her but doesn't it reflect on your system that I paid manually and she said it does but she cant re-connect because there is an accounts dept that is supposed to call me and fix this. Till now, not even a call and have spent the whole day with a suspension that could have been sorted out asap. This is really pathetic and I want this fixed asap. We agreed that I pay manually and I have been doing that, why then are you debiting my account with figures that doesn't make sense and you disconnect me the whole day. This is unfair. I have kids on holiday and they spent the whole day with no entertainment. can this be fixed now.
