Extra charges and suspension even after paying!!

I have premium products with Telkom Mobile and am paying almost R2 000 per month. I paid this month the same as last month and then my accounts got suspended. I called in and was told there was a shortfall of R68.50 - where does this extra charge come from??<br> <br> I paid it as these services are important to me and I needed it resumed promptly. After paying I called again and was told that I would have to wait up to 72 hours for the payment to reflect and proof of payments are not accepted!!<br> <br> This is completely unacceptable and it's now been a day and a half without these essential services that I require for business.<br> <br> That R68.50 is the last money you will get from me Telkom. I don't care about your contract.
