No coms with vodacom.

My contract with vodacom expired in Feb this year. They automatically extended it .I don't even use their old phone anymore. Went to their shop at South Coast Mall to cancel. They say I must do it on the phone. On the phone I get a long sch**** by a robot telling me what buttons to press to cancel. Then they say I must call a number - which turns out to be the same one I called. Then a robot tells me which numbers to press. Then they tell me a number to call... ad infinatum. They won't talk to me or let me cancel; but religiously take my money every month.
