Cancelled line - still being billed

I lived in George and moved to Cape Town in March this year. I had a Telkom line in George, which I cancelled of course, seeing that I was moving. Since March, Telkom has failed to cancel the line.

I've been on the phone with them on numerous occasions and below is the list of excuses they have given me: - they don't know why the line was not cancelled - they give me the run around by referring me from department to department - they have a back log of cancellations - only 1 person works in the cancellation department - there is nothing they can do until the line is made inactive - they cannot assist me and I need to call a different department

The list goes on and on. The last time I called, they actually promised me that the line is officially cancelled and everything is in order. Sadly, I got an invoice for September and October.

I unfortunately cannot pay for a service I don't use and which I rightfully cancelled by following their procedures. The struggle with Telkom has been exhausting.

I have yet to get a straight answer from them.
