Is it possible to refund/cancel traditional braces after 1 week?

My orthodontist only gave me 2 option which were invisalign or traditional braces, i chose traditional braces as it was cheaper. I only have minor crowding for my front top 2 teeth and my bottom front bottom 4 teeth. I also have a perfect bite. I realized aligners are quicker and suit my situation well as it's quicker and also cheaper for example "Inman aligner". I paid $1000 out of the $4000 already and was wondering if i could some cancel my braces and pay no more or even get a refund?
