Was sold expired samoosa's

We into the store and brought samosas and when we started eating the samoosas we ate one which was rotten. We went back to the store and when we got there the 2 ladies gave us attitude when we showed them that the samosas were rotten. They further did not want to acknowledge that we had a complaint. And further gave us attitude and they did not want to refund us the 4 samosas. This was disgusting service and I hope people become aware of this. I am truly flabbergasted by the poor service.
