No Help for Expired Stock

On Tuesday 17/10/2017 I stopped at Crowthorne shopping centre, not on a frequent route. I called in at Woolworths Food and bought a 150 g box of ****** in Dark Chocolate for R75.99. That Saturday night my wife and I opened it. The chocolate was not shiny and looked hazy, nevertheless we tried it. The first pieces tasted slightly stale, but the next was too tough to chew. We then looked carefully at the box and saw it had a sell by date of 17 August 17, two months before I bought it. On the Monday, the 23rd, my wife phoned the Woolworths customer helpline and spoke to Rhiana (sp?), who sounded shocked, about it. Then we heard nothing further from Woolworths. About a week ago my wife again spoke to someone at Woolworths customer care. This time we were told to return the box to Woolworths Food at Crowthorne! I will do so when one day we go that way again, but I am totally unimpressed by Woolworths' attitude to customers for selling expensive expired goods.
