Finally got my refund after arguing a bit, since they kept repeating themselves over and over ("police report isn't complete", "we only want it in English" and so on), had to threaten them with a police report against them and a chargeback in case they didn't comply ASAP and we're finally done

Well done with not taking "no" for an answer throughout the entire claim.

Perseverance was the contributing factor for Its success.

How safe would it be to use the Amazon's purchase invoice to register this GPU on the manufacturer's website for an extended warranty?
The invoice doesn't mention the refund, nor does the Amazon order page, as it's still giving me an option to return it since 30 days didn't pass, but maybe they could actually contact Amazon somehow to verify the order and I could get in trouble for that?

Unless someone's selling purchase receipts, I'm at a loss here.. or I could try editing some data on the invoice so that it can't be traced to me, and see if they accept that without a double check?

Edit: or, maybe, using receiptmansion.com could work? Is there a store among the free ones that doesn't get checked for sure?
