Bad service expired beers in a fridge

Bad customer service, I bought two 910ml castle lite on Sunday 26 of Jan found two quarts passed sell by date.i opened the first one it was bitter no foam of a beer I pour it out in a drain.on opening the second one I discovered the beer has expired 4 nov 2019. Very disgusting, on returning them in the store the manager told me blatantly that he will not refund me....arrogant as he was he told me that I was lying they don't keep the expired stick.
