Billed for a unknown account

In April 2014 I app**** for a S4 contract with 8ta and started paying R269 from May 2014 in the month of July the billing was R408 I called to enquire and was told that I had two contract. Lodged a complain with case number ***2 and called in since. Later I was told that they did not have a cell number attached to the case I forwarded then the number they stopped the new contract. In April this years I was called that the number will be reinstated, It was working to few days till the billed came which was R3800 and the month there after R1080 I called to ask why they told again that I have two contract. I really give up now. Every time I call the response I get is that the case has been escalated waiting for response from the back office.<br> <br> Cell number ***
