How would you prove your not dead?

'The same thing happened to a good friend of mine. She and her husband went to get their mortgage and SURPRISE! They tell her that she is dead. They even argued with her for a week over it and refused to believe that it was a mistake. They couldn't get the problem resolved in time, so her husband had to purchase the home only in his name.

Turns out her ex-husband told AmEx that she was dead when they wouldn't stop making collection calls. They never verified the information and years later it came to bite her. I guess it never occured to her that something was amiss when AmEx stopped harassing her, but that's a different story for a different day.'
