Item suddenly discontinued

I placed an order for a Samsung Galaxy Tab S 8.4 two weeks ago. The item was advertised with an expected delay because it's a \Hot Item". Today I received a call and the consultant told me that the device had been discontinued by Vodacom because too many customers had problems with the device.<br> <br> Please divulge the nature of these issues and why it was suddenly discontinued? It was suggested that I try and find the device at a branch but that would be too troublesome to try and hunt the device down.<br> <br> """
