Worst customer service ever

It is with big concern that I log this complaint. But I was advised by my attorney that this is the only way I will get response out of Vodacom. I did not have enough money in my account in Feb 2015 for my Vodacom account of R299 to go of as I was without work at this stage. This is my fault and for this I will take responsibility. However in March the funds was there and the Vodacom debit order went of 3 times. I was fine with this as I was in the wrong in the first place. They never took money off after that but I thought the contract was over. No one ever phoned to say that there is a problem. I then in June went to buy data for my boss when I decided to get my upgrade done while I am there. To my biggest surprise my account was suspended. I phoned Vodacom who then told me they stopped my account because I did not pay in Feb. I said to them I have proof that it went of my account 3 times on witch they reply they can stop the account whenever they want to without letting me know. Nobody phone to inform me of this. I payed the outstanding amount. I still get smsed that I am being handed over. If I phone They tell me to ignore this.
