How to return not used game?

want to return Warcraft II and Warcraft II Remastered. I’m trying to do this and during the process I see “none of the products are eligible for a return”. I bought the games yesterday. I played for a few minutes. They don’t meet my expectations. How do I make an effective return? According to the regulations, I have the right to do so within 14 days, as long as I haven’t played for more than 2 hours.
