Who called from 6616702583

ID was "UNICEF", likely soliciting donations. Called several times. I did not answer and they did not leave a message.

UNICEF. They are calling daily. I noticed I'm getting many calls from 661-670-25xx. The Nature Conservancy calls me on 661-670-2568.

Have been called daily, sometimes twice, no message, no greeting.  I consider it harrassment

Caller ID: UNICEF (most likely not)
The scammer did not leave a message on our answering machine.
Our numbers are in the Do-Not-Call Registry.

I'm not convinced these calls are really from UNICEF, or legitimately represent UNICEF. That said, my spousal unit wrote a check to UNICEF last November. Whoever processed that check would have had to copy our phone number from it, and pass it on to this phone-drone company without our permission. Very uncool!
