Vodacom contract

10G has been added to my contract and I have been calling since April to get this resolved because the amount has went up. I was assured by one of the consultants that this wouldn’t happen via email and telephonically and it is July and the amount and data’s keep being debited and allocated. I’ve went to different branches numerous times and was told I just have to call and it will be resolved. I’m really not happy with this because I thought this service provider would be better thaN the previous one.
