Who called from 7808511003

These guys are not nice.  I work nights and they wake me up.   When I answer they hang up.  It is almost like they are checking if you are home.

Received a call from this phone # and didn't answer but they didn't leave a message either.

Recieved a call from this # asking if "Clover" is there. Upon answering "no" they immediately hang up

I called it back and it's some kind of redemption center,

I am in the same boat as you les. I wish they would stay on long enough for me to tell them to eff off. How they got my number I don't know. But as soon as i answer they hang up. It is downright annoying. And it always ruins my sleep.
