I received a call from this number on my mobile. I rejected it as it was not on my contact list. No message left. When I went to block the number, I was notified the number is not valid. I checked with a friend who works for AT&T, the number is spoofed.
Best guess is they are scammers.
I just received a call from 832-016-1976 and I did not recognize the phone number. I did not answer and they did not leave a voice mail. I will block this number.
