I also got a call from 972-624-6001, picked up after the 2nd ring, no one on the other end. If this is a charitable organization they need to hire people who aren't afraid to talk to people on the phone.
I received a call this evening, caller ID states Texas with the phone number. I said Good Evening two times then sid Good Bye and hung bup and looked it up - here I am.
Several calls from this number during all times of day and even 'late' evening hours. Never left messages - suspect of fraud calls. Be careful do NOT give them any personal information...Reported to authorities.
