The teller who called me basically gave me awful service.

I visited the bank a few days earlier because they sent me a debit card that I didn't want. (I wanted to switch it to an ATM card because it's harder to commit fraud with them.)

The teller basically didn't listen to me and tried to push services on me for 15-20 minutes. Eventually he realized I was getting extremely frustrated and helped me do what I needed to do.

The call from the teller a few days later was extremely unexpected, and I was justifiably curt. I said something like, "I don't want any new banking services, there's no reason for you to call me."
