Has called 2x so far - 7:24 AM (PST) and 7:29 AM (PST). I didn't answer and no VM was left.
Have also gotten 7 phone calls between 7 AM and 8:31 AM (PST) from 2 other 404 numbers and an 877 number that have been reported as insurance scams. Besides health, I have made no insurance inquiries in over 6 months.
Got a call just now. "Unavailable" but rang through, which is not supposed to happen with an anonymous caller, so I turned on the phone but said nothing. After a few seconds of me being silent it played some kind of music the disconnected.
Got a call on the 23rd. Callback (using cell with ID blocked) went directly to voicemail. Blocked it.
Just checked the call log and see that on the 24th that number called 13 times from 10am to 8:40pm. Since I had the number blocked, I never heard a ring. Glad that I blocked it after first call.
