No feedback No help Very slow!!!

I'm having a problem since October 31st 2015 I loaded my bis for my blackberry. However no bis service was activate. I called the call centre they said they opening a case and a technician will be in contact with me within 72hrs...today is Thursday 5th November over 72hrs have passed and every time a call the call centre for feedback they tell me to wait for the techicians call. This is frustrating as I need to be able to use my phone because right now it is useless. I am seriously thinking of changing to another network because my tablet I use cell c network and whenever I call the call centre for cell c when I need help they help me within 5minutes!!! However 8ta is prolonging my case and frustrating me out. Please contact me on ***. or my alternate number. ***<br> <br> Kind regards<br> Miss S Chetty
