No device delivery

Good day.<br> On 30 Dec 2015 I did 2 MTN no's upgrades ref no UV***.<br> I have phoned *** numerous times and each call ended up with a different consultant with each consultant promising to get back to me, but never did any of them get back to me and I still do not have my 2 new handsets. One consultant actually phoned me saying the courier could not get hold of me but I had no missed calls on any of my 3 devices. I gave her my daily contact no and have heard nothing from anyone. Why could they not try and contact me with a sms. The area I live in we are battling with the signal due to it fluctuating.<br> My aunt did her upgrade on the same day and she selected the 2 for 1 deal on the Samsung J1. She received only 1 handset as they were short of stock and will deliver when stock arrives. Till date she has not received her 2nd handset of the deal. Her cell no is ***.<br> This is the first time since my first application around 1999 that I have had this bad service from MTN.<br> Quick to say the call is recorded but the follow up service is unacceptable.
