Bad service

On the application of my contract I took out a new line and the lady that assisted me, assisted me well. But I did a follow up at the shop and the staff in the store had bad attitudes (Conny). I requested Conny to call her manager and she advised me that the manager is not in. I then advised her that she must call the managers on the cell, \she advised me she will not, for the manager will tell me the same thing she told me. What service is that. No wonder Mtn is losing there profits."
