Got call. ID says Clinton, MD. Answered and got dead air open line. after a few seconds recorded voice says "goodbye" and disconnects.

I have been on the "do not call" list for years.  This is the 3rd call within the last couple weeks from this number (240-318-1569).  Indian guy selling air duct cleaning for "Home Services Maryland"

I got the same call! I thought it was a prank caller, and when I tried to call back, I got the "this number is not in service" error message. I then looked the number up, and I found out that it was the same scam caller that had called me before saying he was with "Maryland Home Services". Weird.

I have been getting calls from this number for months. I am on the Do Not Call list. It comes up as CLEANING PRO'S (Which is even spelled wrong, since the apostrophe doesn't belong.) I never answer the call and they never leave a message. They just keep calling repeatedly.

Got a call on 12:18 est Thursday 20 feb 2014. No message left.
