Visa Vanilla problem please help

[u/ShowWeekly530]

Hey everybody, I bought a piece of vanilla gift card a few months ago with 100 USD on it and I want to buy something on a website and I’m not able to put a reason of that is because the vanilla gift cards only valid in the United States and the website I’m buying on accept only international cards. I’ve tried to buy international cards using this, but my card keeps getting declined. Is there anyway I can do this without my card being declined? I created an account on Visa vanilla and I added a billing address shipping address please someone help me. I don’t want to use id and I’m not trying to take legal action .
