THEY SAY CRIME PAYS, BUT IT SEEMS THAT INCOMPETANCE ALSO PAYS

I have numerous contracts with vodacom and have been a client since my first cellphone. All my contracts have expired almost a year ago. i requested in February to cancel my contracts, which they haven't done after two more calls the cancelled only one number. since then every time i phone to cancel the other numbers they promise me their supervisor will phone me, which never happens. I had to empty my bank account and move all my other debit orders to another account to prevent them from debiting my account. They are still trying to debit that account and still charging me even though I got rid of my sim cards.
