Selling expired products and no feedback!

Long story short, I've ended up buying numerous expired products from Spar and then took the time to inform them about this via a previous Hello Peter listing (ref nr ***) - that I posted after I first did try to get in contact with the specific store's management without success - they then rep**** saying that they will get back to me and resolve the issue within 7 working days - which they again failed to do - I suppose by not responding they hope that these types of queries will just go away... FYI Spar - there are MANY other local supermarkets to choose from rather! Just not good enough...
