How do I get my badges because in soda saga I'm at level 2737.

Hi @melmess, welcome to our community.  To get more lives from friends you have to be playing the game through Facebook and join one of the groups for that game or if you play through King the friends are randomly chosen for you.  What badges are you referring to?  Are you asking about the badges in this community or in your game?

By the way, you just posted this message in the Candy Crush Friends Saga community but you are asking about a Candy Crush Soda Saga game.  If you ever want to ask any questions for your game, you can look here.  That is the CC Soda Saga support community section.
