I had the same thing happen to me at a Colonel Sanders a few years ago. I found the store knew they didn’t have what I wanted when I ordered but decided to give me something else. I looked inside the box and asked for a refund. The manager flat refused. I just started talking louder and louder until the other customers started to notice. I got my money back.
I once had to deal with a bank that had erroneously turned over my Mom’s $90K account to the state. They seemed reluctant to discuss the problem with me, until I stood in the lobby and stated yelling, “How do you lose a $90,000 CD? What do you mean, you turned my Mom’s life savings over to the state?”
THAT got me the manager in a hurry, but it remained true that they had turned over my Mom’s savings as a delinquent account, even tho she had been in there 4 months earlier - and had the paperwork to prove it. It took 3 months to get it back from the state (AZ).
