Absolutely poor service

<p>I have a telkom contract for almost two and a half years now and this is the first time I have such a major problem with there service. I recently upgraded my contract to a S7 and have the invoice emailed to me and debited from my account. Last month the amount was paid and I have a invoice to say that telkom received the amount now I have been into a telkom store and was told and amount of R1100 was supposed to be paid on the 17th. I am absolutely upset because I don't know where this amount is from and they have failed to give me a proper reason because my debit is due on the 31st as done for over two years. I was told I would be contacted with a explanations and I havent received one yet I have spoken to 3 telkom call centre agents and every single time I have been sent from caller to caller without any help. I have had enough now and already considering changing my network. </p>
