Top Up Contract Still Billed Incorrectly

In April I renewed my data contract with Cell C. All communication was done via the phone. On the phone call I requested that my contract be changed to a Top - Up contract so that we can no longer go over our contract limit without purchasing further data bundle. Cell C failed to change my account over to the Top-Up. <br> <br> We resolved the issue after the cell c consultant went back and listened to previous conversations and it was confirmed that I would be billed R149 per month.<br> <br> This month I was Billed twice R214.99 & R1581.70. Since April I have been battleing to get this sorted.<br> <br> <br>
