Unprofessional staff and not selling what they offer

Just bought two pieces of hungry lion chicken I ate one piece couldn't even finish it , it was very salt and sawer at the same time I asked one of the stuff why does it taste like that she says she doesn't know do I want to take it back I said yes cause I definitely can't eat it she told me there's someone calling me at the back office told the old lady the same thing told her to taste it she said there's absolutely nothing wrong with the meat I told her I just can't eat it she didn't even offer something else she just said they change their spices and now and then told her I said I want the original hungry lion I had to leave the meat there
