No stock on Promotional Items

Following on to my report logged 16:45 Fri 6 Feb my Corporate status has been updated after about 18 days. MTN has advertised a Valentine's promotion in the Yello Trader for the Samsung Galaxy Note 4 (including a cover) and since the promotion was launched on the 12th of February I have been told that there is no stock of the promotional item. I think this is really bad that a customer has to wait almost a month to get a phone upgraded and that items are advertised with MTN knowing that they would not be able to supply to demand. I am at boiling point at the moment and feel like going to the papers and even Carte Blanche with this matter. VERY BAD SERVICE AND FALSE ADVERTISING!!!
