Deals advertised not available - ANYWHERE

First of all, I do not want to complain about the Queenswood branch, they are the most willing to help and I have only good things to say about them. <br> <br> My complaint is about MTN and their advertising.<br> <br> For the last two months the Yello Trader has the Sony Xperia E4 on a R55 top-up contract for R69 per month. I wanted to take that deal, but because of a \dispute"between MTN and Sony the phone is not available anywhere. I would really like to take that deal"
