NO RESPONSE - NO DELIVERY

On Monday 9/11/15 took new phone to MTN Allandale Rd to repair centre, fault on phone. After inspection they confirm CAT phone is faulty. Got collection number for new phone. Cant get one at MTN shop because previous one was delivered. Must also be delivered. Spoke on Tuesday to Joshua. He said he will arrange for delivery. Must get RIM? number for delivery. Will phone me back. No return call from him. After a struggle I got hold of him on Wednesday. Same story. Waiting for number. Thursday same story. Will phone back in hours time. Nothing. Spoke to Roger. He promised he will get Joshua to phone me. That was 11.45. No 14:00. And guess what????? Still no response. Need this phone urgent for my work. I want to cancel this upgrade. Would appreciate it if somebody in the right position can contact me to do it. I did\t expect this from MTN as I'm a client for more than two years now. It's pathetic."
