Horrible service but cannot say I am suprised.

MTN service is as appalling as it has always been, no surprises here but becuase it's already been 2 weeks since awaiting for a response I am just compelled to complain here s contacting them has proven fruitless. I was due for an upgrade on the 1st of September and reluctantly went to upgrade my son's cellphone with MTN. As expected the service was horrible, first to MTN Mall of Africa where I asked them to cancel the application due to lack of delivery(by the next day my application was still not processed). I then drov to Greenstone to try my luck there. Was assisted by a guy called Siyabonga and I opted for the 2-in-1 deal. There was then an issue activating the second sim card and I have been to greenstone, called countless time to follow up on this activation and since then Siyabonga has been promising to call me back with further developments on my query which has been going on since the beginning of this month. We are now sitting with an unactivated sim card for over 2 weeks and now he is not even returning my calls. How diffucult can it be to activate a simcard? MTN will just never disappoint with bad customer service.
