Very bad service and NO feedback of any kind!!!!

Me and my mother went to the Tzaneen branch to do a change of ownership from her name to my name. I was due for a upgrade and we did everything the same day we were there for almost 2 1/2 hours but I was very happy with the service I received. From there it went downhill. I received a invoice via mms to say that I will pay R667.00 of which my contact is only R349.00 pm. I was not imformed of any extra charges, and if I was informed that change of ownership has a fee I would have simply cancelled the contract on my mothers name and opened a new contract on my name. With this bothering me and wanting to fix this I phoned in more than 10 times and not one of the consultants could tell me whats going on, they all put me on hold to \calculate something"and then the phone got cut off and then I phoned again. This happend every time. The one consultant logged a call but I have not received any feedback. Reference *** and ***. the change of ownership that we did is not even done"
