Incorrect Charging and Worst Customer Service Ever!!!

<p>I received an account from Vodacom indicating out of bundle data usage for an amount of R658 extra.I could not understand this because the tablet is most of the time off in my cupboard or if on its connected to my wi fi. Every month so far out of the 500mb I receive I carry over more than 400mb.I contacted them in which I was informed that they can see I always carry data over and said they going to log a query with their data back office and that the fault looks to be on their side.I received a ref nr *** and I was informed that I will be contacted. About four days later my phone rang with a +*** number and when I answered nobody talks and they put the phone down. This happened two times on seperate days so I contacted their customer care.The agent was so rude when I told him the situation not even properly introducing himself and told me I must start answering my phone and keep it with me.I told him to transfer me to someone that is willing to help in which the call was cut off.I phoned again and told them to have this data office contact me as the number they calling from cannot be reached.They phoned me again and as soon as I picked up it went off.Yesterday I received a SMS from them saying thank you for your support and that my query is now closed!!??I have been with MTN, CellC and Telkom Mobile and never in my life experienced such pathetic and rude non service.Vodacom I am not going to pay your overcharging amount.If you are looking to make money look elsewhere.I see on Hello Peter I'm not the only one with this issues.I will be awaiting your call of correction.</p>
