Cancelled Contract but still being billed

I called th contract department on 8.7.2015 to give 1 month notice to cancel my 24 month contract that expired on 7.8.2015. I was then convinced to not cancel, but to take up a R75.00 x 24 months contract for 1gb data per month, which I accepted on 8.7.2015. This new contract would start on 8.8.2015 (day after previous contract expired).<br> On 10.7.2015 - I called and cancelled this R75,00 x 24 month contract because I changed my mind and will not be using the sim card anymore. I was given a *** and told that the confirmation sms will follow.<br> Forgetting about the sms - I took it that the contract was cancelled, but logging into my account found that I am being billed.<br> 15.9.2015 Ref Tshidi 4:48 I requested them looking into the matter and get back to me. I suggested that they listen to the voice recordings. They promised they would and get back to me.<br> 23.10.2015 Ref: Lesego 16:29 Again suggested they listen to the telephonic recordings which they said they will and get back to me. Today is the 7th of November 2015 and I have not received an sms, email or a call yet. So what must I do now? <br>
