Upgrade and Sim Wop

WHAT THE HELL IS GOING ON WITH YOU PEOPLE???<br> My wife had an upgrade done on Saturday, 24/01/2015. Immediately the GPRS settings were deleted of her account and she had no internet access since. The Sim swop, to an LTE sim card, took till Yesterday to go through. AND STILL NO INTERNET ACCESS. We phoned your call center probably 30 times over the past few days and everytime we get told: \please switch the phone of and remove the sim card. then put it back in and switch the phone on". They have also been cutting our calls since yesterday where no one wants to speak to myself or my wife. We went to an MTN store last night and had another simswop done as the problem does not seem to be with the phone. And now it seems that we are starting at the beginning again. Call are cut when we call the call centre"
