American Express killed my card. But I’m glad. You see, the address of my account was changed and American Express attempted to contact me using the phone number and it was changed. Since they couldn’t get in touch they emailed me but that address was also changed. No reply meant that they killed my account. I found out at Target and confused called them up. Since I haven’t moved, changed my phone number and switched out email addresses I had them put it all back and change all my passwords. While I was initially annoyed that the card was declined, I was ultimate extremely grateful for their anti-fraud systems. So all I can say is thanks Amex!
