strange calls

I have an account with Visa. For the past couple of weeks i keep getting these calls saying we'd like to offer you this or that because you pay or bill on time every month. I always hang up on them. Anyway, they call today and he goes into this speil and gives me the last four digits of my card and what not and the he says are you still receiving your mail at XXXXXX, I hang up like I always do. then something strange hits me, I realize, that he gave the addy of my (special mailbox) I get tons of things sent there but also my "Jose canseco books" anyway, I call Visa and they say they dont have that address or the phone number he's calling from anywhere on file. Its always the same phone number but different people, and they sound professional, anyone else have this, heres the number 727-541-0001, its in clearwater florida, mysterioulsy in the same place as getpinz is located..hmmmmm

Interesting.....

they offer me crap because i pay my bills on time, however how do they know this and how do they know the address to my box and my cell phone number

I would be worried if I where you. Seems like (hypothetically speaking of course) if you where to subscribe to any overseas Jose Canseco fan clubs and order "books" with a credit card one of those fan clubs may be selling your information. I would be worried that they where calling to gather your pin number or something like that. Don't tell them crap!
