utter incompetence and rudeness

Upgraded my cellphone package from an open line to an MTN my choice 500 which might I add I was only allowed to do once my outstanding amount was settled in full. (2000+). I paid my account and was *****ed around with getting my phone. It took me over 3 weeks to apply for a new phone via MTN active, I app**** in Feb 2015. I chose a my choice 500 package because I did not want to pay over 1000 a month on my phone. I cannot afford over 1000 that is why I chose my package. Every time I recieve an sms telling of the amoumt outstanding I go in and pay cash because of late payments from my clients and debit orders. Today 08/06/2015 was the absolute last straw. I have been told that I now have monies outstanding since September 2014. I have also continuously been suspended a week after payment since i upgraded. I want nothing more to do with your pathetic services any more. I have been shunted from pillar to post trying to figure out what is going on and today I find out I am on an open line again after specifying that I dont want it. I am not paying another cent towards my account. This messes my business around which causes me to loose money. Im going to another service provider.
