I'll never buy from them again

On Thursday I bought food at Steers Ghandi square I was extremely disappointed they have a SANHA approved certificate but they served me haraam meat when I went back to complain the lady at the till had an attitude talking about me as if I don't exist then the manager came he doesn't even look clean and they working with food his nose was dirty. I ended up getting upset because he can't prove this food is halaal I left without any food or my money back.
