I just received the following alert from my bank, and they want to verify that I made these transactions:
Do you recognize all of these transaction(s)? Approved transaction at PETRO [redacted] for $1.00 on 09/21/2018 Approved transaction at CHEVRON [redacted] for $1.00 on 09/19/2018 Approved transaction at CHEVRON [redacted] for $1.00 on 09/19/2018
The dates and locations match times I've used this credit card. I'm assuming these are preauthorization charges, but I've never noticed them before and this is the first time the bank's alerted me for them.
