I want my bill sorted and be refunded

I agreed to a contract of R349 pm. However am billed irregular amounts and when I called to enquire, I am being told that the contract is open and cannot be changed now as that is an amendment. I merely requesting to that Vodacom must keep the agreement of R349 per month as per my application . If they captured an open contract on their systems , I am not aware of that and that is quite frankly not my problem.

I addition, an insurance was taken in my name while had informed Vodacom that I do not want it. This is *****!!
