I didn't answer because I was suspect of the number. After I looked up the number here, I have saved the number as D N A Do Not Answer, so I won't wonder next time.
They have called me a couple times with the first requesting that they take me off their list. It is an automated message completely in Spanish. At the end of the message it directs you to push 9 to talk to someone so I did. When a male picked up I told him that I speak English and he hung up on me.
Canned message in English about their Government Grant Scam. Although other sites mention messages in Spanish and that they are threatening and sometimes sexual. I have not personally experienced that.
The message I get says to press "1" to speak to someone or "9" to opt out. They do not stop calling so the opt out is no good. If you press "1" you will get a message to leave your information for them to contact you.
