Being overcharged and no one can say why

To start off, there is not enough space in the nature of complaint field!! But anyway here goes.<br> <br> I upgraded my Vodacom contract via the website on the 12th of June 2015, and as always when upgrading in the middle of the month, the new contract only starts the first day of the following month. Come the 4th of July 2015, I get a sms stating that my account has been soft locked. I then proceeded to phone Customer Care and got told that I have reached my credit limit on my account, which is impossible in four days!!<br> <br> The lady I spoke to logged a request for me that no one responded to, I phoned again on the Sunday and the Monday, still nothing. Received sms stating that I have to wait 2 days for them to get back to me. Eight and I repeat 8 days later my phone was finally unlocked with no explanation whatsoever other than someone charged me for my handset three times.<br> <br> Then wake up this morning getting a sms stating it has been locked again!!!!! Day 9 now for this ****! An hour phone call and lots of shouting later I just received a sms stating it has been unlocked. No phone call apologizing or offering some reimbur*****t. O and can they pass the buck!!! Still no explanation!!!
