MTN worst customer service provider

Shocking experience with MTN, they don't have any stock whatsoever for tablets. It's a school requirement for most schools and they cannot give me an indication if they will even get stock, nor when. Their response is that it's not them it's their suppliers. Surely this industry will be prepared for school requirements. I'm so appalled by the consultant in store, when I walked into store he was busy on his cell phone. Wasn't very helpful, just said they don't have stock and it's not their fault, blaming the suppliers. Surely MTN should order enough stock knowing that there would be sales. A week ago I was told I would have it this week.
