caller left no massage

They call me every two days or so. The first time I called them back and they asked me to give them a 1-5 rating even though it never said for what, and it was for a "day of service" when we had nothing done. I've saved them as "Don't Answer" in my phone until I figure out how to block them. VERY annoying.

I get calls from this number all the time as well. I've never answered it because I typically do not answer unknown numbers. I figure if it's something important, they'll leave a message. I've not ever received a message and when I call the number back it rings several times and then gives me a busy signal.

This number calls me every other day. It hands up as soon as I answer. I call it back and it hangs up on me too. Never get through to anybody. I have blocked out on my phone but I can still see they aee trying. Would love to know what this is!

They call every day and hang up.
