scam report

Good day this morning I was browsing a particular book since I want to buy it, competition from @Amazon .co.uk appears I though is legit because to my understanding they sell books. I have entered the competition I won 1000 euro according to the advert , then they sakes me to fill my details I did in order to claim my price. I dropped it when they ask if I m working, bank account. after that I browsed their website to view if it is legit only to find that is scam. I can find their email address I want to report . I m scared they will scam me with my details. anyone who can help please assist.
