Telkom woes

I have now 'upgraded' twice in the last 4 years, each time with multiple issues. It would seem that if you use direct debit Telkom are not interested in solving problems since they can just continue charging. I suggest that if you wish to upgrade possibly a better way of doing it is to cancel all the present package and restart as a new client. My latest upgrade was done 6 months ago and I am still being overcharged by over R100 a month plus a cellphone account that was cancelled is also being charged for monthly despite my having confirmation that it was cancelled.
