Ripping me off and Consultants cannot fix problem

January 21st 2016 I received an SMS from Vodacom about additional 2Gig added to my account, the next day I called 111 to have this canceled as I do not require this on my account, spoke to Neo Masilo who advised that it was canceled but due to the fact that an apportionment was already credited to my line I will be paying extra for that month end, which I stupidly accepted! Last night I received the same SMS again, called this morning only to get told this service was never canceled on the 22nd? So why waste my time if no one knows what they are doing. This is not the first time this happened, about a year ago I experienced the exact same problem with Vodacom, this is a *******, now I will have to pay once again because someone in the call center did not know how to do their job properly, I believe that person should be held accountable for this billing and not the clients. They should listen to the call records and will then realise that the client is not in the wrong, their uninformed staff is to blame!!! So sick of this company, come October when upgrade is due I will cancel both my contracts and look for another service provider!
