********** activity on my account and vodacom refuses to assist me and give me my refund and answers as to how ***** happened on my account. I'm literally being ignored and told to pay for something I don't have?

I have been a vodacom client for over four years now and every time I upgraded I would go to the store. I've never done it online. I only have one number but recently I picked up 5 numbers now under my contract without my knowledge and what pains me is that they were upgraded without my knowledge online. I was not called nor informed I don't know who authorized it. I didn't sign anything agreeing this ********** upgrades. I call vodacom ***** they tell me to do an affidavit and send my ID signed three times. I have been paying so much on my vodacom account for something I don't have. I'm supposed to pay 3500 a month now I have to pay 6500 to 7000 a month that's like buying a new phone every three months and I haven't upgraded my device since 2020 so u can just imagine the inconvenience. Now they are taking advantage because I made arrangements on my account they are saying they will remove those numbers but it's been two months since I've have been waiting for a response from their ***** department and my account keeps going up and I'm really frustrated who authorized the upgrades? Where are there devices? Because I don't have them. I wasn't informed and their legal department is so rude telling me they won't remove my those ********** numbers on my account because they know it's an inside job. I've never upgraded online. I always go to the store. I just need those numbers removed and my refund back because this is not fair and on this is a serious ******* for clients why don't you have strict systems to prevent ***** on your clients accounts. No one willing to assist me on how that happened I am being avoided and I'm told to settle arrears of something I don't have this is sad. Vodacom is the worst
