Well the thing is after doing the placement matches in 1v1, they decided to put me in gold league. But the thing is I have played like 20 matches and lost all of them. I certainly do not deserve to be in this league and should be in bronze or silver. Is there any way of just going to those leagues or am I stuck with gold?
You're pretty much stuck in Gold as of this moment. If you really want to be placed into Bronze or Silver you have to keep losing. If I were you, I would rather try my best to win because eventually you'll get out of the lower leagues.
Every time you lose, you learn something. Utilize it as best as you can and perhaps you won't deserve to fall anymore.
I'm in platinum league and I definitely feel like a gold player, but I personally enjoy playing people better than me because i get better. So, enjoy it.
