On the 8th April I went to Mr Price canal walk and got a few items for my son bare in mind that wad the last items that was in his size. I went to the till ready to purchase the clothes to be told that the system is offline I ask the cashier to set it aside for me for the next day I wrote my name and surname contact number and the date on a piece of page and the cashier advised that she will set it aside for me I told that I'm coming back the next day cause that's the last sizes of the items. The next day the 9th April I went to the store and got myself some items aswell and went to the till and told the cashier that I set aside items the day before and gave her my details. She told me she can't find my items and told me that unfortunate I would need to go look for the items again. As desperate I was in that moment of time I went to go look for the clothes only to find that the clothes I wanted the sizes were no longer on the self which cost me to look for a different set of cloths and yet again look for his sizes. Went back to the cashier that assistant me and asked to speak to the manager she got the manager and I told her how upset I was for what has take place and all she told was that she is sorry. Is this all because I'm a coloured that I received this service from them because I strongly believe that if it has to he a white person they would never have received this poor service from the store and their items would never have been placed back onto the railings. I'm really disappointed with this service I've ever experienced with Mr Price 1st I had issues with your call center agents and not with this store what next ? This is pathetic and to think I went all the way from Mitchell's plain to century city to get this items to get this disgusting service. They definitely need to be trained how to work customers and to show more emphaty towards customers.
