Glass found in my zinger wing

Hi so two days ago we decided to buy KFC. I ate most of it, but when I got to my last piece... I bit into it, felt like I broke a tooth, and fearing I'm going to fish a piece of my tooth out of my mouth, NOPE... I got a nasty sharp piece of glass instead. Now I don't know what to do about it but guys please be careful. After I complained about the event on social media more people contacted me and shared with me that they also found glass in their burger the same night I found in my chicken (zinger wing)
