CONTAMINATED CATMOR FOOD

THE BELOW MAIL WAS SEND TO CATMOR/RCL FOOD ON 20APRIL20, NO ACKNOWLEDGEMENT OR REPLY In March just before the LockDown we purchased 18 packets of CATMOR VitaCat food from our nearby checkers store. One of my cats was fed (one teas**** each as a treat) from that packet, very shortly after that the cat started to vomit. During next feeding time, both of my cats were fed from the same packet, again one teas**** each. Both cats did not eat the food, sniffed on it and walked away. This has never happened and makes us think something is wrong with the content. Please advise. I am sitting here with 18 Packets of the same food which I will not feed my cat. I have no till slip anymore to prove to Checkers I had bought from them, hence I now ask you how to handle this for reimbur*****t for my purchase. MORE IMPORTANT: there is cat food out there which is contaminated.
