Calls several times a week. No message, nothing.  Been on my blocked list for months now, but I have no idea what type of scam they're trying to pull.  

Calls are daily and sometimes twice a day. I finally picked up last night and they hung up.

I get phone calls every single day from this number and when I call back I get answering machine  it does not exist.

Caller asked my name then hung up

Same as above. Caller ID comes up as Name Not Found.  Left no message.
