Contact upgrade mess

I have checked this morning on my phone via mtn *141*5# my contract upgrade eligibility and it showed 26/03/2016 which is today. So I went to the Mtn Service store in Menlyn for my upgrade, to my surprise after waiting 2 hours for service I did get told that I can only upgrade from 1/05/2016. This is really a joke that MTN can't manage or maintain their services, I did show the sale consultant as well that it show that I can upgrade today via *141*5# he was just as surprise as I am, but obviously didn't have any answers. I ended up spending half a day go to the store waiting 2hr for service and traveling back home all for nothing. It so embarrassing that a big company like MTN 's systems are such a mess and then wasting their own clients time which they can't replace and then on top of it all you can't get an proper explanation.
