These jerks call multiple times per day from early morning to late night and hang up as soon as you answer the phone.

unsolicited messaging

Answered and they hung up. Called back and had a unavailable service message which was very faint and distant.

calls me all the time.

I've gotten on an average of 3-5 calls per day from this number. The first was an automated message that "this was not a sales call". Other messages have been from live callers, but they're calling from a cell phone with terrible reception. They all ask for a name that is not mine. All I've been able to do is put them on my block list, on my phone.

Called called after 8:00 p.m. Unknown research group calling my cell phone.

Recorded message in spanish; have received at least 3 calls. Annoying.

They call 3-4 times a day... no message, no voice, nothing! I tried to call back...no dial tone!
