Expired medicine and rotten food

It has been 3 weeks since my initial complaint to Spar Head office and 5 emails later and I am STILL awaiting a response from Spar other than \Thank you we have sent it to so and so."!<br> <br> Here is the list of my complaints:-<br> <br> *Spar Heather Park George sold me medicine which was 11 months past its expiry date(Creche Guard Omega brainfuel chews). I had already given my son two of the chews before realizing the box had expired. He complained later of a sore stomach and had diarrhea. ***.<br> <br> *Upon speaking to a manager at Spar about the expired medicine and physically taking more boxes off the shelf to show him what is being sold in his shop (some of the Creche Guard Teens medicine expired in January 2013)"
