So sorry to hear, but hang in there. You are not the first and you will not be the last to be left feeling wronged by such a 'clinic'.
Have you considered SMP to perhaps lessen the effect of the patchy areas...? That could perhaps be an option if you do some serious research and go to the right people.
Either way, there will be some light at the end of the tunnel eventually. Many people have been repaired here. Stay strong.
No matter how upset you get, just keep hanging in there. Give it time. This too shall pass.
