MTN advertising phones that they do not have

I'm helping someone do an upgrade and she's on MTN.
So I check the MTN deals for February, and find the "Samsung Grand Neo Plus" in there.

Irene mall - no stock
Mall @ Reds - no stock
Forrest hill - no stock
Centurion mall, never answers the phone so I drive there to visist both stores - no stock
I then register her on the MTN website to use MTN direct, but there is something wrong since nothing comes up when you search for upgrades:

So eventually we try the store in Potchefstroom and their response is that they have not received any stock of it thus far.

So half of February is gone and none of the stores have stock(but are very willing to sell us a more expensive alternative)?
