Contract Renewal without NEW Device-very frustrating experience.

Renewal without getting new device- It seems that MTN does everything to force you to renew contract with a device upgrade. The Karaglen- Edenvale store certainly tried their best to frustrate me so much that to make life easier I would upgrade the device as opposed to just getting airtime & data only. I went to the Rivonia-JHB store and the consultant renewed my contract with only Airtime & DataI-It was expensive but at least I did not need to get a separate contract for a Mobile Router and then pay Migration fees???? (migration from what to what?- I must give full marks to the consultant at Rivonia, she explained to me my options and why the Karaglen store lady wanted me to get a separate Route contract. Though the renewal process is not finalised as it needs to be done on the 27th of this month (when my contract finishes)-so if anything goes wrong again I will be back! I am ONLY TRYING to renew my contract WITHOUT getting a new device. So my bill went from 749.01pm to +- 419.00pm and am getting much more Anytime Data. BEWARE of NightTime Data-it only kicks in after midnight-most of us are sleeping at that time, so you pay for something you don't use and then have to pay extra when you run out of Day DATA. If I thought other cell phone providers were any different from MTN I would have changed provider-but they are all the same- Customer DOES NOT come first. No matter what they advertise.
