Bunch of *****s

I have been a loyal customer to vodacom for years now, so one of my contracts expired last year in december already and i got billed, i went to the store and was told to cancel the contract a 1st for me but nevertheless i did so, one of the consultants on the phone tried to force a data bundle on me on my other number that i still have. As per our conversation, i TOLD the guy I'm not interested as that contract expires July 2020, to my surprise the operator load a data bundle onto my account without me giving him the permission to do so, i phoned vodacom numerous times but nothing till this day, its been a week already and nothing happen
