Who called from 6147544060

These guys keep on calling. We had to block them even after asking them to remove.  Comenity Bank or something like there.  Apparently a tenant gave them our number

Called 2 times in 1 hour, when I answer they don't speak and hang up!

They call from this number and another ... 720-456-3684 - 5 calls so far today.  They will continue  calling up until 8:55 tonight.  EVERY DAY.  I have a service that automatically takes "robocalls" away after one ring ~ so I don't answer it.  It just goes away.  STILL ... very annoying.  If this truly is a debt collector as others seem to indicate, they would have no reason to be calling me.  I have 2 credit cards - and I know which banks hold them.  It's not COMENITY.

i was recently scammed, not picking up the phone with unknown numbers. they are not leaving any more voicemails either, just keep calling.
