Upgradeing of line and incorrect billing

My line was upgraded without my permission and billing was incorrect!!!! I called to sort my account up and got told to call MBD.I called MBD and Telkom and a few times and asked is this amount to pay till my next payment is due and both agreed yes pay this amount and your account will be sorted and reactivated.... I paid the amount! few days later my line is suspended and handed over and my name listed!!!!! which is incorrect(legal requirements are that an account needs to be outstanding for 30 days and I need to be notified ). Which I was not for this new amount. I clearly asked your call centre agent and MBD give me the amount till the next payment date and you guys gave me the wrong information and listed me without a letter or the account being 30 days old!!!!
