No warmup? No introduction? Just right into "I'm so-and-so" or "I'm with AOL" and then "can I have the name of your AOL account please?"
Freakin' weird. Sounds kinda scammish if you ask me. I mean you gotta figure just randomly dialing people in the phonebook you've got a good bet of hitting someone who has AOL. Probably 50% of the time or more.
I believe this calls for you to string them along and find out what's going on. Make up a fake name, see if they take it. That should tell you if it's a scam.
Oh yeah, after this, call AOL in your best "8 levels of pissed" voice and tell 'em to stop f%$#ing calling or else.
