... except that I haven't changed my behavior and the 'reasonable' action they took was permanently locking me out of my account. Note that they presented this whole experience to me in a foreign language because obviously my GeoIP is the same as my location because privacy, China and VPNs don't exist. And of course, I had no choice but to leave that number on record because it matches my credit card address. Because of course, there is no such thing as a credit card with an address outside of the issuing country, or someone that lives at many addresses or an address where there is no reliable mail. It's basically a number of bad assumptions layered with bad customer service and algorithms. Every year my credit card company randomly stops my card because they think it's weird a transaction occurred in some country or other. I say "See how I just bought a plane ticket right before that? How is that strange?". Right on my card it says "World Mastercard". I have or have had accounts with this same bank in 5 countries. They know this. But we can't just blame the bank, it's the credit card system. Apparently in every corner of the world, idiots run these algorithms. Finally, note that for this wonderful experience I pay 5% of USD$1000 = USD$50. The US intelligence sponsored monopoly of card companies on payment has to end.
