They called and I missed it. I called back and it was busy. I called multiple times for 2 hrs and it was busy. I call back later someone picked it up but didn't say anything except in the background they are talking with someone. They then hung up on me. I called back. Busy again. I think they are either telemarketing or a scam. Not sure which. Phone number reverse search identifies it as a Comcast land-line in Annapolis, MD.
