Billed for cancelled services

I'm not going to write an endless list of complaints about the number of times I called the call centre in the past couple of months about my issue, without getting any type of resolution to my problem.

The bottom line is I cancelled both my ADSL and Telephone line months ago, and I'm still being billed for both.

Every time I talk to someone in the call centre they say they'll escalate it. Can someone at Telkom please just sort out the situation as there is no use for me to even call anymore because no one can tell me what's going on.
