They have called me twice, once on my home phone and the second on my cell phone.  On the call to my cell phone I asked them what vehicle they were calling about and they didn't know.  They hung up on me when I insisted on knowing which vehicle they were calling about.

202-495-7127 is Car warranty  and the same  offering  won free trip.  They still call after you ask Do Not Call.  Their other phone number is 909 842 9107 (C.Cali, possibly Catharine, Ontario California) 909 842-9176. They have other numbers and have  called for months.  I guess I will have to return their calls until they get the message at their prime time. :) I have been return call: Mutual Consolalidated Savings " reduce your interest rate" also. If enough people get upset, they might not be able to phone and  they'll get the message. Remember "Do onto others as they do on to you":)

Called and hung up upon my answering the phone.  ANNOYING!!  We are on the DO NOT CALL registry.

I'm on the do not call registry as well and couldn't figure out why I was getting more calls.  A friend sent me this link about the problems with the registry:  http://www.goldhawk.com/consumer_news.php?consumer_news_id=168

Who are these people?
I am on a do not call list in Canada but this does not seem to stop telemarketers from the US.
I do not answer these calls but they are frequent and annoying. They never leave a message but often call multiple times at 5-10 minute intervals.
I am going to do what was suggested in another post, try to block this number with my telephone company.
