This hand-waving about fraud is complete nonsense.
The banking industry shrieks about fraud and chargebacks yet gyms, which are basically the scummiest retail businesses on the planet aside from payday lenders, are allowed to use the ACH system and get direct access to money, not credit - that is a royal pain in the ass to revoke?
So much so that my state has an entire set of laws devoted toward curtailing the gym industry's various shitty cancellation policies? I believe they're even prohibited from requiring ACH payment - they must offer other options.
And what about all the local newspapers that make it impossible to cancel? Or all the made-for-TV product companies?
Brick and mortar is a whole different ballgame.
