I had someone set up an amazon.mx account using my credentials somehow.... they ordered a bunch of online books, include a $1200 textbook. I have no idea how they were able to do it.

I was able to get them to reverse all the charges pretty quickly, but I still get messages from amazon mexico saying i should buy stuff, and for a while amazon.com would ask me if i wanted to go to amazon mexico when i logged in.

I have only been to Mexico a few times in my life, and my spanish is really bad. I have no idea how it all happened, since they didn't seem to be able to (or didn't) change any settings that would lock me out of my account.
