Lack of Sense

So I've been with Telkom Mobile just over a year with no issues. This is all started back in the month of September when I decided to switch bank accounts so I figured I'd let them know of my new banking details, called them and they took down all the new details and advised me over the phone that the debit will go off the following month, I fairly agreed. The first month was fine however in October I had an SMS stating a debit has been rejected from my previous bank so I called Telkom up and the Agent tells me that the previous agent who I initially gave my new details to saved them onto the system but didn't select them as new details, he then said I should make a manual payment. I overlooked the matter and made a payment of R400 into their Absa account..in November I don't get debited however I get a statement saying my account is in arrears and I only paid around R30, I called immediately and told them I have proof of payment and was told they don't accept anymore, I then asked to speak to a manager when I was told there wasn't any available, asked to speak to a supervisor and was put on hold for over 25 minute's before disconnecting the call. <br> <br> Yours Sincerely,<br> Mr Unhappy
