2012 Toyota Camry Le Window Problems

Hi, I recently purchased a 2012 Toyota Camry Le. When I first brought it home,
the driver side window would get stuck about three quarters of the way up, but
it would eventually go back up. I haven't messed with it since (about 1 week).
Today I tried using the window again and it is totally messed up. When I roll my
window half way down, it keeps going down regardless if I'm pushing the
button or not. Th window will not go back up all the way, it is stuck in the
middle. The window doesn't look steady either as it is moving out of its mark.
There are no motor sounds when I roll the window up or down either. What
could this be?
