Upper Tribunal Rejected permission to appeal. What next?

HI

I would be so grateful if someone will help me with my case.

I appealled to First Tier Tribunal and Upper Tribunal and both have rejected permission to appeal stating that there is no right of appeal.

Now i want to know what are steps to take for me to fight against them. I want to know court of appeal or session but dont know about it. please tell me procedure for that. and any form to fill up.

thanks.
