Online services that set auto renewal as default are such a fricken scam.
Your credit card expiring doesn't even save you from the phantom charges if you don't notice them, because half of them have agreements with card services to get the new expiry info.
PAY ATTENTION. If you're ADHD/ASD like me, it is so easy to forget this crap. But I did the math, I have lost over 5k to these unused services in the last several years.
So be aware, be vigilant. (I say this while on hold with Wix who I am trying to get to refund me a $487 charge for a dormant unused service.)
