Credit card companies fraud alerts don’t always make sense. My brother went to FLorida a few years back to work hurricane claims- he was there 8 months charging living expenses and paying off the balance every month when the credit card company decided some sort of fraud was going on and froze his card. When he called them they said his activities out of state had triggered a fraud alert- we really laughed about that- seems a crook could have used his card 8 months before the company would get excited.
A few years ago, I had to drive 3,000 miles round trip between our properties about once a month, for over a year. Every time I stopped for fuel (same truck stops each time, no less) on each trip, I would have to go inside & call the CC company to verify my identity "because it didn't fit my profile. Same at motel desks. Got tiresome.
What was worse, was the weird one-offs that they DIDN'T question!
