When the AMX card # was stolen the first time there was a $1 charge in Bangkok. Then it was backed out a minute later. Then about an hour later a $59 charge in Australia and a $35 charge in New Zealand.
Apparently the $1 charge to test whether the number is good.
I had used it a day before at the local Thai restaurant. Somebody there probably sold the number to their cousin back home. I called the owner and told her. Never heard another word. I also stopped going there.
The only other time I got an email alert and text from AMX was when I charged my BullFrog hot tub. It went through, but my wife and I got multiple alerts
I know they are a bit of a progressive company which I don't like, but they are extremely good at what they do. And they do it well.
