TELKOM internet service delivery problems

I am having a great deal of problems with my telkom ADSL internet at Klerksdorp and Lydenburg Branch. we have franchises all over SA and we have been loyal clients for years. I contacted Telkom, but nothing was done. So I then called to cancel Klerksdorp branches subscription. They didn't so n stopped paying my invoice and they cut of the line. which is fine because I got new internet service. recently I got an invoice for over 4000, where it should have been around R700???<br> <br> I called telkom again and up to date I still haven't received the cancellation form.<br> <br> CAN SOMEONE PLEASE ASSIST ME TO GET THE INVOICE AMENDED AND THE SERVICE CANCELLED.<br> <br> KIND REGARDS<br> <br> Louis Fourie<br> cELL: ***
