Vodacom arrears after full payment?

Early in September I requested a quote for the full amount I am owning and to do and early cancelation of my contract since I wanted to open a new data contract. You did send me a quote and informed me the full amount needed to end this contract was R4,710.69. I paid that asap (16 September) and then went to the Vodacom shop to confirm that my account was paid up and done. They checked and confirmed and app**** me for the new contract. It was immediately approved (which would not be possible if I were in any arrears of course). They did inform me also that there would be a small pro rata fee for the data they added for the rest of September and a sma admin fee which I would see on the next statement. When receiving my Statement I was surprised to notice I am owing R475. 95. Contacted the shop again and the lady said she cannot understand why I am being charged extra after paying the full quote amount. We phoned customer care and they claimed I was in arrears.

My monthly subscription is supposed to be R299. The admin/connection fee suppesed to be R85. Can you explain why you claim I am in arrears?When the full amount of your quotation was paid? And why is there a contract cover plus of R2 when I specifically asked not for? Please explain fully.
