"Unknown" at 234-512-3451 called at 6:29 am, 8:44 am, and 9:55 am this (Saturday) morning. I didn't answer any so I don't know anything more. From what I read this is not unusual.
Called at 6:22 a.m. Saturday morning, then again 7:33 and 9:48. When I call back I get the message "call can't be completed as dialed or number is disconnected." Caller ID shows "name unavailable." I'm on a no call list and consider this harassment, especially since they do not leave a message.
This number called both my business and my cell. Both times I answered (like an idiot) and whoever was on the other line, hung up! When you call it back, it's a fast busy signal.
