Been suspended even though I have payed

I have an ADSL line with Telkom. They sent me a warning on the 4th, telling me to pay or they are going to suspend me. I did pay on the 5th of January. On the 8th of January I receive a sms from Telkom saying that my account has been handed over to VVM Debt collectors and that I should contact them regarding my non-payment. So I phone this VVM Debt collectors and inform them that I have indeed payed 3 days earlier. So the gentleman on the phone says he will inform Telkom that the payment has been made and that there is no reason to be suspended. It is now the 12th of January, 7 days after I have paid my bill in full, and I can't get hold of them, as when I phone, the machine informs me that I am indeed still suspended and that I should either wait another 48 hours or email them on [Email Removed] I emailed them yesterday and I did not receive any response from them. I have a commune and my tenants pay to have internet, and my internet hasn't been working since middle of Dec 2015. I can't get hold of them and they are charging me for something I am not receiving. And my tenants are becoming more and more upset with me, even though I have done everything I could.
