I have refused to answer calls from this number, but they are very persistent, calling daily for weeks now. My phone is registered with www.donotcall.gov so this number is somehow excluded from that process.
I haven't figured out what, if anything, I am going to do about these calls.
Called--I answered and said hello, the caller hung up. I will not answer if this call appears on my caller ID again.(reading one of the above posts, I recall last year I got some literature from that group--right after one of my credit cards had been hacked into online. I called the toll free number and told them to remove me from future mailings. They called once after that, and I told them I was on the do not call list. They claim they are a marketing firm that sends training CD roms to people)P.S. I threw the disk out--never put it in my computer or DVD player.
