Leave me alone

I have been getting about up to 5 calls a day from some 800#. Most times, I just ignore it and the don't leave a message. They called again today while I was at the shop and this time they left a message. I dialed my VM and, there was nothing there, just static. Just a bit ago, I got another call and was asked by an automated teller to enter my Credit Card number and SSN. WTF, sounds like bull shyt to me. I did some quick googling and found this:

HSBC Fraud department says this number is NOT connected to them. When you dial 800-395-2274, an automated voice says, "Card Services" and asks for your account information -- it is obviously an identity theft scam.

That's nice
