I need help, someone else has my phrase seed, how do I change the phrase seed

Hi, I have a seed recovery problem, someone else contains it because they changed the password 2 times. but they have not stolen the 5 dollars that I have in bsc but I have an investment in plant vs undead and they have access to that nft game. Can I order a new seed so as not to lose my investment? Is there a solution?

Sorry for my bad english
