Unhappy Customer

I am getting my contract billing doubled - Its started in April where I had to pay double my instalment because I had supposedly not paid in February. Then May came and they advised that I had no money due as I had paid already which was obviously the double debit in April. We had now gone and paid at the end of June and the amount due was 2 & half months, I only paid for 1 month as I should have and I called Vodacom who advised that nothing is due only the 1 month instalment which the operator could see was paid. A few days later I get smsed a bill of double premium and a few calls from Vodacom advising that their is money outstanding after numerous calls and going into the Vodacom shop and being advised that all is in order.

How many other customers are charged double debits when they should be going off monthly? we have budget and allocate a certain amount of money for your phone bill to be *****ed around by faulty systems/consultant errors this is not ok and I am very disappointed.
