Went through the drive thru at about 10:15pm. I ordered a 5 piece tenders with fries. Was told there would be a 5 minute wait for the tenders, which I was fine with. Parked in the front and the person behind me parked next to me. When the worker came out he asked, "you had the 5 piece right?" I said "yes". He handed me my food then started to walk to the other car, he suddenly turns around and says "oops, that's the 3 piece!". So he switches bags. I should've checked before leaving but unfortunately, I decided to wait til I got home to check. Was given a 3 piece tender with macaroni and cheese. At this point, it's already 10:40 and I'm not about to get back into my car and drive back to the store. So I decide to call and let them know, literally called 4 times and it just rang and rang with no answers.
