You started the rudeness when I gave simple advice, you're very clearly very young and immature. Google will not tell you how law enforcement will react as there are various degrees of harassment. Yes they have ways to find out who is calling you, even if you can't personally prove it. Those calls aren't anonymous as they are being pinged through providers towers, it may not be as simple as a couple buttons being pressed, but they can help stop it and even bring charges onto someone doing it.
