Bad client service

I bought 4 zinger wings for lunch then when I got to my work place I took 1 wing and broke the piece open to find the inside is yellowish in colour and when I took it close it was smelly so I went back to the store where I showed the lady giving out the orders and she called the manager who I told her my issue and before she could even look at the meat told me she has never seen rotten wings and called out that I must be given my money back with out even asking if I would prefer to be given the money or change the order, she continued saying that is the spice that am seeing and took the wings and my slip claiming she will use it to someone else. The manager was very rude and not even cared about my complaint.
