MTN Poor service

In week of the 15th Oct'15 I went to MTN store in Newcastle at the Newcastle Mall to submit document to do an upgrade. I requested the Samsung Note 4 in Gold colour, after about a week and querying about the phone I went to the shop only to be inform it has not arrived, the following day I again queried and was told the phone has arrived. I went to sign the contract only to find out a white colour phone was delivered, I again informed them I would like the colour gold. During this week I again queried if the phone has arrived but still none, on Tuesday I phoned couple of times but not getting answer at the shop thus I decided to go there in person. This day I spoke to a different person and he informed me that the gold was not available anymore and the person that assisted me initially (two weeks back) should have informed me about this. I then agreed to take the white phone but this was then no longer available and I was informed that they will contact me the following day to update me , no calls received, again when to shop over the weekend with no phone received. Complaints lodged on MTN site but not response from them except automated return mail.<br> Pathetic service MTN.
