MTN have no clue on whats going on!!

Good day, once again I have a bad experience with MTN.... I have been requesting a date on my upgrade due date, when i called in the beginning of Jan 2016 requesting an early upgrade i was told i cant do it and have to wait till Feb 2016. I called them again 27-01-2016 and was put through to the sales department and a lady confirmed that i can do my upgrade on the 1st of Feb 2016 and this was the second person to tell me this. So again i called MTN on the 29-01-2016 to check if the deals they have on the website will be valid on the 1st of Feb and NOW i am told sorry you can only upgrade in April. This is extremely ridiculous coming from one of the biggest Cell operators in the country... Its seems that MTN staff don't know what they are doing, and their managers just don't give a damn. If my business is not good enough I will gladly take it somewhere else. I was told i can do the upgrade on the 1st of Feb and I expect someone to assist me with this. Again if me business is not good enough i will take it somewhere else. I expect a call ASAP from a manager regarding this disappointing service from MTN!!!
