Samsung Telkom Galaxy S10 rewards

Hi

I received a SMS saying I had won a Samsung galaxy S10+ thus morning from a site that appeared to be Samsung & Telkom which is a South African service provider. I filled in my details as the quality of the website and the content seemed legit. However my alarm bells went off when they asked me to pay R30. I filled in my details but when it came to requesting payment I got weary. Their web address said thegiftsonline.com and when I read down its talking about a subscription service and you can get a chance to win the S10 in a draw. I immediately exited the site. Its scary because it seems very legit but you must read it through
