Terrible attitude rotten cheese

Good morning..i had a bad experience with checkstar in overport.i bought cheese at the time but didn't notice that it was bad. When i got home i saw that the cheese was green i went bavk to the store and the manager was very rude .the store is really dirty The trolleys are filthy they do not clean them.The managers are not remoseful.You can go blue in the face talking they just look at you.They have no ethics at all and talk to their staff rudely as well..How they have staff like this I've no idea. Management shouble to be taken to task
