I have been receiving calls from 1-661-670-2560 everyday, more than one time per day. No message is left.

Got a call here, too. Didn't answer, no message. Inclined to believe with the above posters - probably DNC..

No message was left from this number 661-670-2560, but shortly thereafter I received a call from 240-330-6135 from a scammer claiming he was going to take legal action against me.  (He claimed he was "John Castle", from the FDA.)  I am pretty sure the FDA doesn't contact individuals this way.

I'm blocking this number, getting multiple daily calls.

We have been receiving calls from this number for over six months. They ask for my husband, and the response we'll call back later. Quite an annoyance.
