Threatening calls

I just got yet another call from the Home Center. 925-384-0997. I told him to take me off his list. He said if he couldn't call me he was coming to my house at 3 pm. I asked if he was threatening me and he said, "Yes. If I can't call you I'm coming to see you. I'll be there at 3 o'clock." I told him I was calling the police.
