I work at a bank call center. One time I had someone call to check the balance on an account they recently opened with us. The bank I work for is regional, and this caller was on the other side of the country. The account number they gave pointed to an expensive private school in our area. When I asked for more information, the caller said they gave someone 500$ to open the account for them, and that person gave them some checks from us with that account number. I got my lead on the line, did some more Q&A, and we determined this person had been scammed, and given fake checks. The lead said they would close the account. The next week I get a direct message from the fraud investigation team director asking me why this account wasn't closed. I was able to provide a screenshot of the message from my lead saying they were going to close the account. They thanked me and that was it. I went to check on it, and over 60,000$ in fraudulent checks had cleared the account in that week. I've only been working there a few months, and I'm 60,000% sure they would have dropped me like a hot potato on the spot.
