That would make you default on the payment and they'll pass it to debt collection. Only do this if you reasonably tried everything else (and documented your attempts) before using that option.
Maybe rules are again different, but a simple subscription here wouldn’t cause a default as there was no credit agreement. Interesting to see how things differ.

It probably depends on if the bill is post-paid or pre-paid. If it's post paid (for example, you pay at the end of the month for services provided during that month), then you do have a credit agreement.
Yup, this is why you should always sign up using a credit card, never your debit card or bank. You can issue a chargeback online pretty easily with most credit card companies these days, it won't affect your credit, and the money never leaves your bank account.
