Re-connection charges when account was paid.

My service was disconnected and I called the call center on 23 Aug to get the amount to pay to reconnect my service. I got an amount to pay of R441 (which correctly included the re-connection fee) from the auto reply voice, which I paid immediately (using internet baking). The service was however not automatically reconnected, so I called the call center again to speak to an agent, who told me that was suppose to pay R441.45. I then immediately paid an additional R1 and she reconnected my service. On the 28th Aug my service was disconnected again even though I had paid. I called the call center and was told that their systems were down on the 23rd when I made the payment so my payment did not reflect, and that I should send proof of payment. They since allocated that payment but still charged me a re-connection fee on the 28th. I logged 2 requests to have that re-connection fee of the 28th Aug reversed as the services was wrongly disconnected since I had paid. The re-connection fee has not been reversed until today. It cannot be that the company charges me re-connection fee when the issue was their system being down. This is ********* business conduct. In fact, it's ******** business conduct. I want that re-connection fee reversed.
