worst service ever

I bought a chicken and mayo pie from wild bean caf? on AZ Berman drive but it was either old or over cooked so I took it back.there was no mayo and the chicken was brown. they called the supervisor who told me I was trying my luck and I bit too much of the pie. I showed him a photo of where I spat the rest out. he basically told me to get lost and refused to give his name and the managers name. I think that's disgusting.
