TELKOM - PLEASE CANCEL YOUR BILLING AS WE CANCELLED OUR SERVICE 3 MONTHS AGO!!!!!

We closed our Telkom Account 3 months ago due to interrupted,/no service/ a 3 month old modem not working and also incorrectly linking another person's number to our line for over 12 months! and then incorrect billing for services not requested and duplication of numerous items on billing. We are elderly pensioners and hardly ever use Telkom anyway. We had our registered phone number for over 10 years so because of all our issues we cancelled our phone line and all services . We tried getting assistance in every way possible including visiting all the Telkom offices and shops to NO avail. WE ARE STILL BEING BILLED AND ITS NOW SITTING OVER R3K. Telkom is not getting a cent more from us.
