CUSTOMER SERVICE - WHAT SERVICE?!

About 4 weeks ago, on a Sunday, I took my Sony in for repairs at MTN Cape gate - 1st they couldn't pick my contract/phone on their system. Eventually they found me on the system and booked my phone in for repairs, to be send away on the Monday. I called the repair centre a week later to be told they haven't received any phone. Phoned MTN - just to hear " we haven't send it in yet". Another week went by - again my phone hasn't been send away for repairs - apparently the consultant was on sick leave. No manager available to talk to. Last Thursday I received a call - My phone is ready! So I went to collect - after waiting a hour to be helped, I was told that I need to wait another 15 minutes for their safe to open - then the consultant came back to tell me they gave my phone to another customer!! This is really unacceptable, I was told that they will deliver my phone on Friday - I waited the entire day Friday, no one called, no one delivered. I phoned and again no one was available to talk to (no manager). Then eventually someone called , just to say that I will only receive my phone on Saturday. Saturday 17:50 someone arrived with my phone, with just a sorry. Now this is really not on! My id details and everything was in the box that was given to someone else!!! MTN needs to compensate for this. Really not impressed at the moment!
