Iwas charged 32$ 4 days after I canceled the free trial and I'm having trouble finding a way to get refund.
The best way would be to contact support via Chat.
However, I couldn't find any plan (Trial or paid) associated with the email address that you used to post here. Is it possible that you used a different email address to sign up for the trial? During the trial, you must have received a few emails from Adobe; check the email address to which those emails were sent. Sign in using that email address and then contact Adobe support.
