unprofessional and misleading

I was contacted by Mfundo Wandile Ngwane from Mobile talk call centre offering me a better deal on my current data package.<br> I was told that this deal would replace my current data package and that I would just need to return my current device when I receive the new one. On the 30th November I made exactly 10 calls to get hold of a manager to find out why I was **** to. I was told he would call back. but he never did!! I find this unacceptable. I required this to be sorted out immediately.
