Appalling Service from Woolworths Mall of Africa Store

The service at the Food section of the Woolworths Mall of Africa store is appalling! I got there today and ordered a pizza slice, the lady there put it in the oven & just forgot about it and left it(and us) there. 20 minutes later after I asked one of the other ladies what's happening with my pizza, she opened the oven and it was as black as charcoal. When I told your Foods Department Manager, Tinyiko Mthombeni, she was just as rude and said that there's nothing she can do about it and I should just wait again for another one to be made, she didn't even want me to take a picture of it, that's how shocking it was. Surely this can't be "The Difference" that you guys talk about.
