It's an unproved hypothetical situation. What would be your recourse if your uncle started reporting false debts to your name whilst you were travelling around Italy?

In the past I have contacted YouTube Red support in the past when I didn't cancel my subscription after I moved counties and they easily refunded a few months of charges. Unsure how that would play out if your account was cancelled. I would probably just contact my bank to get the charges blocked + reversed.

Call your credit card company. They can block a merchant, perform a chargeback, and/or issue a new credit card number. I don’t know the rules for a debit card, but you’ll at least be able to get a new debit card number.

A chargeback? Lol
