I want this but to cancel byzantine gym memberships and other reoccurring charges. Currently trying to cancel a gym membership that won’t answer my calls, reply to letters and insists I have to come in person from 3000 miles away.
The much-maligned Google assistant did sound tempting for this, though. Something willing to call every single day and sit on hold indefinitely to convey a simple message would be awfully useful for the less-illegal forms of membership stonewalling.
Ask your credit card company to issue a new card, and file chargebacks for charges that came after you attempted to cancel the service/membership. At the very least, that might get the attention of someone at Byzantine empire.
