Shirt service from vodacom

Vodacom and their kack service. Ok so I decided to take an I phone 11 on contract at vodacom 4u at South Gate. Fine we go there the consultant gives us the phone and everything we sign and it’s all good, before we live the is an issue that the consultant choose the wrong phone colour which makes everything wrong however the manager says we can leave and they will sort it out. We leave and we happy. Next day we get a call that our contract has been changed the initial contract that was signed is no longer in existence and vodacom created a new one of their own and approved it without my knowledge I mean what the **** with who’s money. I go back to vodacom I am told that the manager said I have no choice but to take that contract I can’t change it what’s done it’s done I mean what the **** who’s paying the contract with who’s money. So I have a contract that. I didn’t sign for with vodacom and am told the is nothing I can do about it. Ok . 3 days down the line I get debited I don’t know what for. Vodacom what must happen now
