same thing just happened to me...I knew it was a scam, but was curious if those numbers matched my card, thinking that they somehow stole my information, but I see from here that they use the same four numbers 4626 for everyone. Not very nice, indeed!
I received the same email from phone # 313-330-0734 directing me to call 734-516-7113. This is a scam. Another way to tell its a scam is the "alert" said the card started with 4626, anything associated with a credit card (or even your SSN) will use the last four digits.
