I don't know where these people are getting my number, but this is getting ridiculous! If I don't recognize the number, I will NOT answer.
My caller ID also said "Gustine" CA.
One of the comments mentioned that it was the police calling for donations for a charity. First of all, the police are too busy to be calling. They use police as a front to collect money. Even if they are collecting for a charity, if you ask them directly how much goes to the charity, and if they are honest, you will find out it's about 7% or less goes to charity. So however you look at it, it's a scam. I blocked the number.
