Didn't want it to get to this point.. but helpp!! 😣😣😣😐

How do I go about getting a court order DNA test and get child support done for my daughter and a potential father?. I had given I'll call him (pedro) basically is okay with abandoning his daughter, but i gave him a chance to step up and do it voluntary, but never had the balls to do it on his own. I recently contacted "Pedro" not that long ago and oh would you look at that, he has officially blocked me on every social media that there is, so I can't contact him at all. I know he has a girlfriend and she doesn't know about us ...but it's been long enough and I want my daughter to know who he really is and she deserves the world.
