TELKOM NOT RESOLVING ADDITIONAL CHARGE

Last month I contacted Telkom because of an additional charge on my account. The consultant informed me that she could not explain the additional charge but that it was an error on the Telkom billing system. I logged an issue as I could not pay the amount they were asking. They informed me that they would come back to me which they never did. When I contacted them again, they told me that they could not resolve my issue and I asked them to tell me how much I must pay as to not have my account suspended. This amount I then immediately paid. This month I received a bill again with the value added again. THIS TIME THE AMOUNT SHOWS OVERDUE!!! AGAIN NO REASON OR CLARIFICATION AS TO WHAT THE EXTRA CHARGE IS FOR. TO DATE NO TELKOM REPRESENTATIVE HAS CONTACTED ME ONLY A STUPID REFERENCE NUMBER SENT VIA SMS. ***. PLEASE TELKOM RESOLVE THIS ISSUE!
