So recently i have sent my card (RTX 2080 that i have bough about 8 months ago as the RTX feature didnt work and it was under performing.) to the ebuer (Thats where i bough the card) for them to ither fix it or sent me a new one as i had a warranty on it. It took about 4 days for card to arrive to them and after that i have been emailed that they wont do anything about it as there is no serial number on it as i have romeved it before it was slowly detaching because of the heat that card was creating and i have put a sticker to a box but im not totaslly sure if that sticker was serial number or not ass that was about 5 mouths ago. I just would like to know if there is a way of getting a new warranty sticker.
