Put simply, it shouldn't. I'll help fix this when you have a chance to forward on. (We stop recurring payments when a business closes their Stripe account, which looks to not have been the case here.)
Assuming user has issued chargebacks 7-months back to back — why would this not be a signal Stripe needs to understand why and not keep charging the customer; one would think even one charge back from a vendor for a specific customer subscription would require re-authorization by the customer being charged prior to Stripe sending another charge.
What am I missing?
