Just received a telephone call from these people on my private, unlisted cell phone. I am also on the Do Not Call List. Thanks to the poster who provided the link for the Do Not Call List, as you can make a complaint against someone who continues to call. Haven't read the requirements yet for making the complaint, but will be checking into it. Thanks to everyone who is sharing their own experiences with these type of calls. This website is really hepful.
This is the second call in two days from this 571 area code which shows somewhere in VA. I know nobody in VA. I don't call back any number that is not familiar to me.
