Does the Gameflip Guarantee protect me against "stolen codes"?

So I’ve been reading about Fortnite STW in this website and I’ve seen one post where they were saying something about stolen credit cards and getting the code and selling them online… My question is if I accidentally buy a “stolen code” (one that gets an error or something after a while), am I still protected or no?

I’m looking to buy from this

If your code gets revoked, yes, you are protected.

You will need to contact us and send proofs that the code was revoked so we can continue to provide you further help.

Thanks and let me know if you need any further help.
