i've just received a letter from a company called Protravel saying Ive won 50 pounds in Amazon vouchers from the Nestle Kitkat Lucky Breaks and Tesco competition. They want mevto complete a form with my namw, address, email address and phone number. They are not asking for bank info or any money. I dont remember entering comp but use tesco regularly so is possible. Is this a scam? Ive googled and Protravel seem legit
