Samsung Galaxy Note 4 Black

MTN really needs to get their act straight. How hard is it to get hold of a Samsung Galaxy Note 4 Black? Yes, I know there was a strike but how did they get hold of all the white colours they currently have? I have left my numbers with Musa from 808 (Call Center) and Thembi from Alberton Mall and I'm yet to get a response from them. Thanks to Paul from Killarney Mall but still he also has a white Note 4. I'm really thinking of letting my contract to expire and just port to another service provider. I also struggle with Network connection when I'm home. I have been loyal to MTN for the past 15 years and now its time I re-think about them.
