Calls at all times and doesn't say anything.

I got the same call and our number shuld be unlisted

i thought it was a bill collector and the internet confirmed it thanks inernet

Called, no message.

I get at least one, frequently 3-4 calls from this number daily. They ask for someone who is not me and then hang up. It is an automated call, but I want to know how to stop it. This is getting seriously annoying!
