Expired Alchol with no Excuse

I bought a castle lite limited platinum edition. only to find out after drinking that it was feeling a bit off and I looked at the date and it was Best before May 2015 and the date I bought it was 23 December 2015. this is so unreasonable Tops very disappointed our health is at risk all they could say was we can give you a refund. after that they took my can trying to destroy it for evidence they even took all the beer remaining in the fridge and hid it. I hope I don't get sick.
