We got the exact same "John Pierson" call at 2:23 in the morning. According to my mother, this is not the first call she's received. We are on the Do Not Call registry, so I went right to their website and filed a complaint. Their website is www.donotcall.gov. Complaints can also be filed online with the FCC, though I don't have their address handy.
I did not answer the phone when this number called. Called back and a message said to press 1 if I wanted to be placed on their DO NOT CALL list, so I did. I believe this is a survey/telemarketing company.
