I get at least a call per day from PDR2. Post was correct, Internet search provides no info as to who these bozo's are. Stop calling, jerks. If I don't know you, I won't answer the phone!
I received a call from this number. It looked familiar so I answered. Caller asked for the head of the household, who I reported was not available and would he leave a message? Was told "oh, this is just a nonprofit call. Thank you. Goodbye." He hung up without me even acknowledging his remarks. I called the number back and got a recording: "Thank you for calling Share, a call center for many nonprofit organizations. If you were recently contacted by Share, it is probably because you have been identified by one of our client organizations as a member or supporter. Feel free to leave a message...." A BRIEF scan of google-search results for Share Call Center identified a couple job postings--in MD & NC--one of which referenced Children's National Medical Center in DC. Caller ID was PDR2.
I called back and it was Share calling for non profits..I left a message saying to not call again (after nightly calls for a week). Will see if it stops.
