Pathetic Service

I went in to buy something to drink as I was extremely thirsty, I bought a 330ml of Tropica orange dress, I took a few big gulps as I was extremely thirsty and afterwards I tasted a nasty after taste and there was residue at the bottom of the juice. When I checked the expiry date, the date had passed already I went to the shop to complain and they say they can't do anything because I already drank the juice and continued with their day and just left me like that . It wasn't about the refund its the acknowledgement the fact that the staff doesn't check stock regularly to see shelf life is really alarming.
