Unhappy client-BAD SERVICE!!!!!

Vodacom has messed up my account, meant to be a contract then I get debited almost R1000 without my consent or even being sent an invoicing with a bill to call vodacom and to be informed its for the phone I am now on prepaid? Then Ive been informed my contract has now been activated after they apparently loaded a passport number to my name but I have an Id???? Yet again calling vodacom asking where my money is as my contract that has apparently been activated needs to be in credit but im not?

Seriously this has been the worse experience with you people, the departments are messing up so badly. So they take clients money and where does it go to if not to my account???
