Several calls daily. No one on the other end. Rings twice and then disconnects. when you try to call an automated voicemail comes up saying that if you received a call from this number we should call again shortly. There is no option to get a person on the line.
I called the number and got a recording, but it did allow me to press 1 if I felt I got the call in error and wanted to be removed from their list. We'll see!
