Disgusting Service

I don’t vodacom deserve any star in terms of their service.I have been battling to deactivate a service that has been activated on my other number without my knowledge. I am on a top up package and I got a bill that was more than my monthly subscription, the 1st month I went to Vodacom Eastgate and the consultant told me that its a billing error that will be fixed.2nd Month I called customer service and thats when the agent advised me that there is a reoccurring data bundles that was deactivated via USD which I was always under the impression that top up should give 1 peace of mind as there wont be any extra charges unless I call in and authenticate but with Vodacom its not the case.I have since been asking that the bundle be deactivated so I can be able to cover the arrears amount but I kept being told that I have to pay up the outstanding amount which I cannot be able to pay all at the same time as the extra R172 was never on my budget.Vodacom went again in April statement charged me that R170 even after I called and asked for this to be deactivated so i can be able to pay the arrears amount for the previous months(Feb&Mar).if I am going to keep being charged for something I never authenticated till June, how do you expect me to renew my contract when it comes to an end or will I be told I cannot cancel the contract till I have paid the arrears amount? All I have been asking is to deactivate the bundle then I will make arrangements to pay arrears amount
