Can you dispute PayPal donations?

I should dispute the donation I made to UnlockPhone.me. They gave me a non working code. Their terms say you can’t dispute anything. I should violate their terms and dispute the charge.

Their site also falsely advertises, says the donation is $10, it’s actually 10 euros. Which is around $16.

No dispute link, you can mark it as unauthorized. Call my bank and tell them to cancel it.
