My worst record was 10 mins, in a CellC store. I had just received an iPhone and it was lying on the counter. There were staff coming and going out the back all the time. This lady came out the back, said "is that the iPhone" picked it up and went into the back. That was the last I saw of it. She must have ducked out the back, as when I asked another staff member where this large African lady had gone, she said no-one like that worked there. The manageress tried to say I was talking nonsense, but another staff member said she thought this African lady wanted to go the toilet. I phoned the SAPS but they did not come. Centre Security was even more useless.
Since I had yet to sign anything, they had to give me another, but I had to wait an extra 10 days while they "investigated"
