TERRIBLE EXPERIENCE WITH CALL CENTER AGENT

I have a been a loyal customer of cell c since 2006. Over the years dealing with cell c on My upgrades was a breeze. Now even getting assistance is a nightmare. I called cell c on Sunday night to do a limit increase on my account..I spoke to the most terrible call centre agent who I never wish to deal with again. Her rudeness and bluntness is pathetic..my query is still not resolved to do a simple monthly limit bill increase. I asked her if we gt a reference for the call,she advised when she cuts the call I will.get an sms. She did not allow me to rate the service I recieved from her. No sms has been recieved. I need assistance from cell c. I need someone to listen to her recording and take the appropriate action.. there is no respect towards customers over the phone.pathetic experience. I was very happy to deal with cell c previously. It's now pathetic
