Who called from 2016437915

Got a call from this number today at 2:15pm. I did not answer as I do not pickup for people that I do not know. If it is important they will leave a message and I will call them back. Good thing I checked the internet.

Calling everyday and leave no message so I called back and number is disconnected weird

Called, static line, heavy southern accent, ask for Mr.D. not my last but first name. Sounded odd.

Called and left some background noise on the answering machine.

This number comes back to a company called Donor Services, Inc.  They do money sucking services (telemarketing, direct mail, email, etc.) for non-profits.  Just another candidate for my blocked numbers list.
