No one there? Ringing phone disrupting your work? I just blocked this new number and no more disturbance. If you add a call blocker (I use Call Control on Android) you can program all the Portfolio Recovery numbers and have peace of mind. They use illegal tactics to trick you into saying things they can use against you, so do NOT talk to anyone there. Just block their calls.
Here are other numbers these scum suckers use:
