Bad service and attitude at Versace store Mall of Africa

I had made arrangements with Perfedia at Versace Store at Mall of Africa to put aside two items for purchase yesterday which was Black Friday. On my arrival all the way from Pretoria only to find out one item has been sold out. No one bothered to contact me nothing! The lady had a nerve to tell me it's a sale item so somebody sold it as if I was informed that an item on sale cannot be reserved for me so I do not bother to go there. She didn't even apologized for this no but argue with me. I ended up leaving with nothing after wasting my time and petrol. I should stick to Gucci or Loui Vitton where I get good service.
