MORE THAN A WEEK AFTER UPGRADE ND IM STILL WAITING

I called MTN on Tue 02/02/2016 and spoke to Kgabo who did my upgrade and said the device would be delivered on Friday 05/02. Because I was on a workshop Friday i gave the Bellville office address. On thurs they cancelled the meeting and i immediately called MTN Direct and asked to speak to him. The anlayst advised that she would take the details of the Plattekloof office and send Kgabo a messag e to call me which never happened. Friday i called back only to discover that the system still showed the Bellville details. Again i was told only the analyst who did the upgrade can update the system. I then informed our reception in Bellville to advise me when courier is there. Courier never pitched and when i called MTN was advised that it eawas still in invoicing. Again I was told the address was not changed. Monday morning i called again and was advised delivery is scheduled for Tues. Yesterday RTT went to Bellville office and told reception they would get someone to drop it today at Plattekloof. When i called this morning i was informed RTT sending phne back to MTN. Escalated to Supervisor KIm Basson who said RTT will contact me n she will follow up. as yet no one called!!!
