VERY BAD SERVICE AND ATTITUDE

I had a Vodacom data contract for a few years now, as well as a normal telephone contract. When the normal contract expired, I was contacted by a Vodacom employee when I required why the BIS of the normal contract was not working any more, and the employee said I had to pay an ex amount extra for the BIS to be activated again after that contract expired. In meanwhile someone took the opportunity to **********ly take out a new contract on my data number with a brand new smartphone without my knowledge or consent. We went and reported it after the mutch increased fee was deducted from my bank account, and they opened a ***** case. After a week or so I was contacted by the forensic department and they confirmed that the case was sorted out, and that I had no fault in it. Because of this bad experience I decided to rather cancel this data contract that the contract period was over in any way, so I cancelled it at Vodaworld. Thereafter I just keep on getting invoices that I need to pay, and I tried to sort this out with the call centre with no sucess. I spoke to 5 different consultants today only, and then I just get cut off and I have to start all over again. It's still not sorted
