McDonald's Elm Rd. Warren/Cortland Ohio Raw Angus Burger! Cortland, Ohio

I'll make this short. The McDonald's on Elm rd Warren, Ohio (consider Cortland)- I went there for lunch a couple weeks ago; I ordered one of those CBO Angus burger combos. I got back to work and was at my desk, just chowing down until I noticed "Man, this burger tastes off"...So, I took the burger apart and sure enough, a big, fat, extremely RAW patty was sitting there...Now, this wasn't even like put on the grill for a minute, it was just stuck on the bun and put in the bag- that is how raw it was. So, I called them and I called corporate (just in case I got sick). I returned the burger and got my money back. Everyone was polite about it, but come on...raw ground beef? I could have gotten very sick.
