Who called from 5203565013

I did just now. Silence on the other end followed by a hangup. I called the number back from a blocked phone and got a digitized voice telling me they were sorry they were unable to reach me, but that an agent would call later when they were free.

Yep, got the same call just now.  When I got now voice I hung up.

Called,  mumbled some company name and asked for me by name.  When I asked the caller to repeat who he works for,  he hung up.

Called asked if I was so and so. Then they said bad connection and hung up.

THis company continually calls and we have asked them to take us off their calling list.   Today I told the girl we asked you to take us off the list and her reply was " you didn't ask me".    
They are continuously obnoxious and rude.   Why should we tolerate her mouth .
