Who is this

Receiving at least 2 to 3 calls a day from this #. I never answer and they never leave a msg.

Answered and they hung up

I had a missed call. I called them back and the call was answered by 'Ashley'. There was no formal greeting with the company name or anything of sorts. I told her that I got a missed call. She said is this Mr. XXXXX and she knew my last name. She started talking about Mortgage rates. I told her that I am not a homeowner. She then gave me an address which was my parents address. I told her I don't live there.

I have been receiving a couple of phone calls and text msgs every day for the last 3 days.  When I answer the phone there is either no one there or a recording that if I want the pain clinic to press 2 or if I want to stop receiving calls to press 9.
