Medical Services Group unknown Wanted my insurance info to supposedly give me pain products Baltimore Maryland

I received a call from these whoever they are today at 10:42 am. As I have caretaker status of my brother and sister in law, both of whom have multiple health issues, as do I, at first I thought it was the UF Health people since we're in the midst of arranging a number of appointments. My brother recently had cataract surgery after being completely blind for 5 years, among other things, and they arrived last year to go under my care, as in CA they were homeless and had no access to a doctor. It was a local number.

The lady had a heavy accent, and was talking extremely fast; I am hard of hearing to start with, so it took me several tries to get the name of the company. Then she wanted to know what pain issues I had, said they had something for me for it, I was missing a ton of words due to her accent and speed talking, and asked several times if they were with UF Health or were they trying to sell me something. When she kept insisting on having my insurance number, which I don't have since I am in City Contract which is through the University of Florida and the city of Jacksonville, and kept excitedly saying "It's government funded, right??" I figured out it was a scam and ended the conversation. I couldn't get a location out of her that I could understand.

I am extremely bothered by the fact they have the information about me they have and where they got it. I keep my medical situation relatively quiet and these people if they get my brother or sister in law's information could potentially really do some damage, as they are on medicaid and that IS government funded. I think they're ripping off the government through people's health plans. I also am very concerned that if they got the information of my name, phone number, and the fact I'm in pain management treatment, what other information do they have that they shouldn't?
