WORST SERVICE PROVIDER IN THE WORLD

I don't even know where to start with my grievances towards MTN. I app**** for an upgrade TWO weeks ago. Still waiting for my new phone. But that is not even what is making me so ANGRY. Your LACK OF CUSTOMER SERVICE is what is making me angry. Your call centre is a JOKE. I have to call TEN times, hold for 30 min and then get told that the person will call me back. AND THEN NO ONE CALLS ME BACK. Or they call me back HOURS later. And then they tell me they need to check something, they will phone me back. BUT THEY DON'T CALL BACK. And the whole process starts over. <br> This has been going on since WEDNESDAY and i STILL do not know what is going on. <br> i HAVE HAD IT!!! CANCEL MY UPGRADE. I want to port to a different network when my contract expires in February. MTN IS THE WORST SERVICE PROVIDER IN THE WORLD.
