It is a scam they just called me and I haven't opened any kind of an account in several years. They want your credit card number to use for financial gain. But as PT Barnum said and they know there is one born every minute.
Called and hung up before I could answer. I'm glad 800notes.com exists. I have a business and need to answer phone numbers that look like land lines - so I am always happy when I can find out something here about a call I missed. This one I can mark "do not answer" and be done with it.
