Who called from 6174332991

No CID. No msg.  Didn't answer.

Caller ID says MILTON MA. This is a robocall selling something resort-related.

called back and says the survey has ended. blocked

No message left, only No Name on CID.  Tried calling back several times from masked line, only got busy signal, indicating the b**tards could be using Call Blocking.  Have received other calls from the same area code and exchange from a bogus survey, no doubt it's the same clowns.

Called at 7:40 PM CID Milton, MA617-433-2991. As soon as my answering machine picked up they hung up and a busy signal was recorded.
