INCORRECT BILLING

I previously posted a complaint w hereafter i was informed by Telkom that my account would be credited. I requested that I be reimbursed. I have not been reimbursed or credited and have again been overcharged this month. I have a contract in terms of which I pay R199 per month for 10GB of data. For the past few months there have been additional data purchases and other charges on my bill. I have not made any additional purchases and do not even have the facilities or knowledge as to how i would make these purchases. I assume that it is Telkom's own personnel who are adding these charges and using the data themselves. This is absolutely unacceptable. I want a reconciliation statement of the last 6 month's charges and I want to be reimbursed as soon as possible for all charges exceeding the R199 per month. The service I have received is appalling!
