Who called from 2143512673

This guy calls my work constantly asking for the president of the company by first name.  I don't know who this person is or what it's regarding but they always get our voicemail.  Very persistant, they call sometimes several times a day.

They called my cell. I blocked my number and called back but no answer.

Just got a call from this number. A man who identified himself a being with the Dallas County Sheriff's Department was trying to raise money.  Caller ID said the number belonged to "SW PR."

Scammer, posing as a charitable organization for Police Officers. Also attempts to get you to switch your Credit Card processing to them.
