Incorrect billing for the past 6 months

I really do not understand what the purpose of being a company that provides a service when you fail so dismally at it. <br> <br> I have been wasting countless hours and airtime calling your call centers to resolve this issue to no success. <br> All I get is empty promises, atitudes from call center agents and no resolution to my issue. <br> <br> Telkom mobile over billed for months, when i requested a refund i was denied. The suggestion was to take the next few months installments from the credit in my account. That never happened instead im still being over billed an the credit in my account continues to GROW...<br> <br> I am so GATVOL over Telkom mobile. THIS WILL BE THE LAST CONTRACT I EVER TAKE WITH THE COMPANY. To be an employee and recieve such foul treatment, how am I expected to promote the brand when I dont get any service worth promoting. Really am not pleased.
