Vodacom is a scan

My contract got upgraded without my concern and I phoned them after finding that out and the lady I spoke to promised to cancel that quote on my name and to my surprise today when I went to the Vodacom shop that quote is still there and we’ve been calling them for the past hour and a half but no one seems to be able to cancel it , all they’re doing is passing me from one number to another and no one seems to know this Ferndale square
