Call from unknown person on my cell phone. Assume a scammer and blocked.

Received about 4 calls from these 2 diff numbers.
339-209-1397
877-375-5540  Just a bunch of loosers who don't know how to make an honest living,so they prey on the old or people who are not sauve about scanners. The callers are DOO-DOO BIRDS

Calls several times daily, never voicemail, no clue who this is...

Claimed to be offering social security disability claim assistance. I asked what company they were with and the person stated they were with: Citizens Disability  Originally called from  # (339) 209-1397 and I blocked it and then they called back the next day with the (877) 531-3242 #. When I asked how they got my email, address, deceased parents names and my # , their answer was "Don't worry about that" after them asking for both my mothers maiden name and father's middle name I ended the call.
