Disgusting sour Koo baked beans

I bought Koo baked beans yesterday , and we always buy Koo as it is a quality product and it was on sale so I took a few cans. I made lunch this afternoon and as per normal I open it up and immediately I heard a hissing sound , almost like gas releasing when you open a can of soda. I then poured it into a pot and heated it up like we usually do . When I tasted it , it was like a bottle of vinegar was poured all over it . Immediately I checked the can the expiration date was 2022 . The baked beans formed a weird foam on top ,I was just so disgusted. I expected better from a brand that I'm so loyal to , I don't even think I'm going to attempt to open and eat the rest. I'm so disappointed . You definitely losing a client.
