highly disgusted

<p><span style="color: #555555; background-color: #ffffff;">To whom this may concern, on 24th June I purchased three trays of the danone yoghurts, they were quite stiff than usual but it didnt bother me I had eaten two of the three trays and today when checking the best before date I realised that they expired the 14th june already, im quite disgusted with this as I am pregnant and been eating expired goods I still have one of the six trays left I have my receipt still so what do I do now as anything could have gone wrong and waisted my money on buying this product. how does a store as checkers hyper sell expired goods aswell they shouldnt have been on the shelves in the first place.</span></p>
