Not true to your word

I was not using my data but the debit order went off every month for more than a year. When I phoned to cancel the Telkom employee told me that if I did not use my data I must phone billing and that I could get my money back. When I phoned billing they discovered that they owe me just over R32000. When I finally contacted them again they contradict themselves and says I was supposed to cancel so I can't get my money back..Talk about daylight *******!
