MBDC need to be investigate. as they reeping us of

MBDC has been debiting my R600 for my woolworths account since august 2014. I called June checking on when is the last payement and I was told it will be august 2015 but I might have to pay manually as it will be R400. Today when I called Prince tell me that I owe R572 as legal fees have been added. I don't understand that as I was not told before. I demand this matter to be sortet out and the debt to be written as they have collected more than what owed woolworths already.
