ATT worker grabbed my phone number and started texting me after setting up my phone

Adam with ATT came to my house to give and set up my new phone. He kept making sure which number was mine, and asking about me. I found everything normal until after he left, I got a text asking to hang out and when I was leaving. I asked who it was and he said it was him. He also implied that he wanted to have (Edited per community guidelines) with me, called me honey, stuff like that. It was disgusting and I feel violated.
