Health insurance phone calls????

I never received a health insurance call until this week and in the last three days,I have received one per day. All have been on my cell phone and I blocked them.

My neighbor takes these calls and does a routine; he starts speaking like someone who has lost it. He’ll say stuff like—“I am really interested in this—don’t hang up—I am helping my grandfather take his bath. Oh, oh—be careful grandpa. You might fall! People hang up immediately.
