I am receiving the same call in Florida. I simply do not answer this call any longer when I see 'Family Support"" on the caller ID. By placing this number on the national do not call list
https://www.donotcall.gov/default.aspx
it might help. I had my number registered on this list last year. Today I filed a complaint with them about this caller. Notice the ".gov" on the address? As much as I have seen the government do for me, which is nothing, I could expect to see the same on this as well. But it is worth a try at least.
