I think I’m being stalked

(Throw away account cause I don’t know if he knows about my other account.) There is this man that comes into my work constantly, I think he’s mid fifties. There are a few reasons I think he’s stalking me. He always says my full name when he greets me, I don’t wear a name tag and I don’t know him. There’s no way he could know me from my family. He used to come into and tell me mildly suggestive “jokes” and ask for my number. He stopped asking for my number but I’ve gotten a few strange calls and silence when I answer. He knows when I work and where I go when I take time off. I know his truck by now and I see it outside my work on more than one occasion. He keeps track of what I wear and how I do my hair. He just mentions a lot of little things most people don’t know. And he’s giving my little gifts now, earrings, hair stuff, etc. It’s just escalating, more calls, more gifts. I don’t know if I’m being paranoid, if I’m not, what do I do?
