I won GameZone Vice Ganda and Regine's Concert and 1-week Canada Tour

GameZone texted me that I won a raffle ticket to Vice Ganda and Regine's concert. I checked the raffle results and saw my raffle ticket code, so that’s good. However, I'm confused because someone also called me and said I won the 1-week Canada tour. But according to the official announcement, only one raffle ticket was supposed to win that prize, and it wasn't mine. That’s where the confusion comes in.

What should I do? If this is legit, I already asked the person who contacted me via Viber if I could give the prize to a relative or sell it, since they said everything would be covered by the travel agency and I wouldn’t have to spend anything.

What should I do?
