If you get ripped off or are having a consumer service issue, here are some things you can do to complain effectively:

This works for overcharging related problems, service problems, unfair or deceptive practices, or the like. Most of these mechanisms get the issue addressed in a couple of weeks:

Internet Products:

Banks/student loans/credit reports/debt collectors, etc:

https://www.consumerfinance.gov/complaint/

Health insurance:

Google "[state where you live] health insurance complaint" and select the government agency that will let you file a consumer complaint.

It's usually an insurance commissioner. Here's the form for Texas:

Cell phone:

Other companies like (home security system, eBay, Amazon, or contractors):

Google "[your state] attorney general consumer complaint."

Problems with your landlord (won’t return your deposit, won’t fix something etc):

google “[your city] tenant advocate.” You can usually get good advice.

If you're in crisis and your life is falling apart, (out of money, need a place to stay, free health care or mental services etc):

Call/text 211. This is usually a local guide to health and social services. It may not be available in all cities.

Do you know any other major sites where you can file complaints? Please feel free to share them!

CFPB is definitely the way to go for anything finance-related. They are quick.
For that situation, the simplest option is often just using the link the OP posted. I had a huge issue with an inaccurate credit report last year and filed a complaint, and the company fixed it within 10 days, zero hassle from my side. Totally bypasses their customer service black hole.
