This might practically achieve the desired outcome, but do note that just not paying does not extinguish your debt to anyone you have a valid contract with.

I've seen Americans living in Europe get bitten by this quite frequently in some countries, where sending something to collections is both commonly done and the collection agency will successfully take you to court and win in almost all cases even for pennies.

On the other hand, the EU has had "two-click cancellation" regulations for a while now, so there is a better alternative available for both sides (customer and company).
