Poor service

Firstly, there's a sign behind the door that says remove your cap. The sign is not clearly visible when the door is open and I pointed that out to security. She rudely told me that's why she's there to tell me that. Secondly there's no queueing system. I was next to be served but a lady decides she's before me and the consultant who was busy with another customer and didn't even notice me, insists that she was before me. MTN's poor customer service is filtering down to its branches. I'm disappointed and will move away from MTN. I can't stand poor service or bad attitude. MTN sucks!
