Bad and disapointing customer service

Hi I am extremely disappointed with the lack of customer service at the Audio department of Pick 'n Pay Lifestyle Centre in Centurion. I was there on Sunday with my son to look at the XBox 360 games - FIFA 15 and FIFA 16 games. These games are locked behind a glass cabinet. There was not price on the game. While I was there another gentleman and his son where also looking at the games. The saleman came and open the cabinet. I asked to look at the game I had in mind. I saw that it had no price nor security tag. I asked him if he knew the price, he told me to go and ask them at the counter to scan the price. I went there and there were three sales ladies sitting there, 2 where helping customers and the other lady was doing nothing. I told that the salesman asked if she could look up the price for me, she in turn said that she could not and that I had to go and find the scanner in one of the isles and scan it myself. When I told her that this was an item that was locked away she said that it did not matter I still had to go and scan it myself. Bear in mind that there was no price or security tag and if I was dishonest I could of taken a game which could have cost up to R 700 and walked out and nobody would have stopped me. I went to the front desk at Customer Care and asked to speak to the manager, there was a gentleman there that tried to make out that he was the manger and when I told him that I do not believe him as he did not have a managers name tag he said that the manager was not on duty. I explained the situation and asked for a piece of paper and I gave them my details and requested that the manger phone me on Monday, which has not happened. This is very disturbing that a locked item has no price or security tag and then I am told to find the price myself as the sales staff seemed lazy and not interested. Regards Jenny
