Yep, Bonneville Collections.  They'll  call over and over. BLOCKED.

Caller requested to talk to me but would not provide any information to my husband indicating it was a confidential call. I am disabled and do not take phone calls. They would not leave a message.

got a call from this number, I had no idea who it was and they did not leave a message.  I called the number back and a woman named Annette answered.  She did not say what company she worked with, only her name, when I asked she only said ""who are you looking for".  
When I said that I might have dialed a wrong number, in an attempt to either break the conversation or get her to tell me who she worked for, she then asked me "Is this Mark?"

This told me that they new my name and phone number and other information and did not want to give out any themselves, so I hung up.
