MTN pathetic

Went this morning to for up-grade & had to wait a very long time to be helped due to the fact that they had a new system & struggled with it. When I was helped, I was asked for a payslip, which I didn't have. I asked her to help me in selecting a phone, which she did, & I asked her how late they were closing and she told me @ 2. She never told me the phone is out of stock. I drove to my workplace for my payslip & was back at the branch at 13h20. Strangely the door was closed, but I knew they were only closing at 2 so I entered. After a few minutes I was helped (by another lady), who told me that they were out of stock and had been struggling to get the phone I wanted. I was upset and asked why they couldn't tell me that earlier to which she had no response. I asked if any other MTN branch in Kimberley had stock and she said she did not know. Another lady (I think the senior of the 3) then told her to phone another branch to check. She did but after holding for a short while, just said that they are not answering and offered no further help. I left at 13h30 to find the store door is now locked, despite them only closing @ 2. I phoned the other branch myself & they also had no stock
