After I bought my new car, I got an email with a header image that looked like it had been scanned from a physical piece of paper, badly. It referenced my name and the bank I had a loan from, but all the domains in the email were not my bank. It claimed I hadn't sent in proof of insurance. I did that at the dealership on the day I bought the car. I ignored it. I got it again and ignored it. On the third attempt, I finally called my bank. It actually was from them, and they really did somehow not have my proof of insurance, and really were going to cancel my loan. I tried to explain to them what was wrong with the email, but they couldn't understand. Edit: In the end, I physically went to the bank to handle it. I didn't do anything else remotely with them.
