A "home improvement" 'offer' from this number is particularly troublesome as the caller-id shows "WITS 2001" which, in my experience, is a tag usually associated with Federal Government agencies. Don't fall for it! I did because I've received legitimate calls from WITS numbers. Now, I'll just let the answering machine handle them.
Called and left no voicemail. Caller ID says "unknown name". Looks like another new number the scammers are using. Almost every call I get from this area code (202) is some kind of scam or ripoff.
