I was wrong to use the term 'fine'. The TCPA expressly allows individuals to sue for damages. The FCC need not get involved.
If someone auto-dials your cell phone, and you can figure out who it is, you can take them to court with a good chance of recovering money from them. If you can prove a willful violation, which isn't necessarily a high bar, you can get treble damages ($500 becomes $1,500). Multiply that by the number of calls.
The hardest part is determining who actually called you. If you can get past that hurdle, the court costs aren't terribly expensive, and you can exact a tidy sum from repeat offenders. There are actually lawyers who specialize in these kinds of cases, and because they aren't terribly expensive to pursue, they'll even take them on contingency. I learned about this through a Reddit AMA with such an attorney. Of course, a determined individual can prevail without hiring a lawyer, provided they're willing to put in the time (and can unmask the caller).
Not sure how that helps when the caller spoofs the caller ID. According to Twilio, the spam call I received earlier today came a number registered a T-Mobile customer named Sharon. Pretty sure the actual origin was a call center overseas. They just picked a random number that had the same first six digits as my own number.
I'm guessing you are not aware of how blatantly anti-consumer our current FCC leadership is. Since the transition they have gone out of their way, even lying to Congress and the people, to pander to corporations rather than serve the people as they swore to do.
