California law requires businesses to let you cancel your subscription online

Very good! Businesses always say they focus on the customer but part of that is also to allow the customer to get rid of them. I still remember the impossibility of cancelling AOL. I had to do chargebacks on my amex for a few months until they got the message.

Comcast and Verizon will be upset

I can't begin to describe the number of companies that set me up for auto-renewal without any form of billing or invoice.

I recently had to cancel an ongoing subscription I had with Equifax, which requires you to call by phone. Unbelievably frustrating. I had to dial the service at least 10 times. Each time, the automated responder would make me go through a very slow menu selection process, only to randomly fail to acknowledge either my correct SSN or zipcode or street number, which I entered using a keypad. As a consumer, I've had to enter info via phone keypad for as long as I can remember, and I've never run into a system (not even small local businesses) that was so randomly buggy.

I thought maybe I had the wrong phone number for cancellation. Turns out, when you google "cancel Equifax phone number", there are several phone numbers listed by Equifax itself, on various sections of its "help" pages.

Took me about half an hour to finally reach a human operator. Surprisingly, the cancellation process was quick with her with no haggling. But I imagine the process is so frustrating overall that a good number of people just give up.

Even so, outside CA the law will go a long way towards removing plausible deniability, and that's something.
