Appalling service and Expired Foodstuffs!

I bought two chocolate bars from PEP store, Mayville, Pretoria. After a horrible session of vomiting after taking two bites from the Lunch Bar, I looked at the expiry date and realised the chocolate was expired. Furious, I returned to the store where I found the manager, Stephina, and told her of my ordeal. After mentioning that I was still weak to stand, and that I had to look for the child I gave the other chocolate to, Stephina insisted, rudely and unconcerned, that I go queue so I may have my money returned to me. After explaining over that I am in no state to stand in a queue, and that someone else could be at risk of eating their expired products, she took a piece of paper and asked I give her my contact details. While doing so, Stephina disappeared into the store somewhere, and I had to leave the half-eaten chocolate, my slip and contact details on the counter, as the manager was nowhere to be seen.
