Poor quality Cadbury fruit and Nut Slab

I purchased Cadbury slabs for myself and family members fruit and nut flavour, quite disappointed that the chocolate was powdery as if it was expired, however it was within shelf life but the quality was very very poor. There is a metalic after taste and a powder like flour that lingers on your mouth. It was like an old chocolate, with grated chocolate powder and very very dry.
