I tried to cancel a virtual card to cancel a service (that only allowed me to change anything by phone call, so this would have been far more convenient and less confrontational) and they tallied up a "delinquent balance" and threatened to sue if I didn't pay everything I owed in order to cancel.
Canceling the card does not work for predatory companies. Maybe for well-meaning ones that automatically cancel when a charge declines.
I switched home insurance away from liberty mutual after my term was up and did not renew. Three weeks after my coverage with them lapsed I received a notice from a collection agency for a late fee for coverage I never purchased. FUCK automatic billing and non-consensual subscriptions.
