Earlier quoted context omitted.
A failed card auth does not remove the obligation to pay. Most vendors write if off, and don't follow-up after a few emails. Plus, they don't want users to get pissed off and post a negative review. Many vendors have now optimized their billing flow to reduce write-offs. They start charging on the first of the month for the upcoming use, and then cancel the account if the auth continues to fail.
> A failed card auth does not remove the obligation to pay. Let them sue over it. They'll just love how the courts would rule in favor of a customer who clearly tried to recover their account in good faith and tried to cancel the billing in good faith and, failing both, canceled the billing in the only remaining way since the company provides literally zero customer-friendly options.
Infact, when disputing such charges with the issuer, the customer always wins if there was an attempt to cancel the service.
