Which again shows the predatory nature of these services, I have run into this sort of thing from multiple providers over the years, I no longer sign debit orders and go without in any situation where it becomes unavoidable. No one has anything I need enough to sign my rights away.
Have you found an insurance company that doesn't insist on debit orders?
@Stonemason seems to have the solution ^^ , that is if one can always use a card number instead of an account number.
