Bad food

If I can give 0 stars I would. Always bought Woolworths food as they pride themselves on quality, freshness and health but on 06 march I bought a club sandwich from the Woolworths at brandwag engen and after eating it i started to commit, have diarrhea and heavy stomach cramps. A day later and my body is shaking as if I am being poisend. Left to say I am never buying food from Woolworths again.
