sounds like a scam...i keep getting e mail saying i won online lottery..50 different times
Just because they new four digits of your acct doesn't mean it isn't a scam. There are similar credit card scams where they actually have some of your info to start. Anyway, best bet is to do what Irexes said and contact their support team directly (not in reply to the e-mail itself) and confirm that this is true and valid.i don't think it was a scam of any kind. they did not ask for any kind of information from me. they were just making me aware of it and they did list the last four digits of the account that was used.
