Weird request from PS customer support

[SapphireMoon]

Doesn't sound right at all.

Besides, I think that PS would be on the phone with you at this point.

Does sound like some weird phishing thing. Don't send it. Period.

Maybe send another e-mail to PokerStars. Don't mention the original concern but ask under what circumstances would a PS rep request such information. - Might be interesting to see what happens.
