Worst customer service

MTN Elridge is the absolute worst store I have dealt with, no customer service what so ever, they never answer the phone when you phone, if you consult with a sales representative on WhatsApp you get told they are busy they will get back to you after 20 minutes which I'm still waiting, I want to enquire about a laptop deal and not getting through to that store, MTN please sort out your staff members at MTN Elridge shopping centre!
