Upgrade of contract

Hello MTN<br> <br> I have been requesting an early upgrade on my current package from last week.<br> <br> Tell me straight am I going to get or or is it declined.<br> <br> I need to know if I must move to a new service provider because honestly you'll do not have a f**%!ing clue how to treat a customer, the call centre said 3 to 5 days and I keep on holding on and no one picks up the phone when they do everyone says they will find out and call me back.<br> <br> F**$! your customer service and network. <br> <br> People rather move to Cell C or Vodacom if you want a better service MTN is useless.
