How can I proceed now

You file  a civil contempt case against Car service providers fo rwhich punishment would be 6 months imprisonment or fine or both for non compliance of court order or defiying  or not honouring the court order,..The court  orders him to be in jail till he honours its judgment.

If any party  deliberately does not comply with the order of Forum then remady isu/s 25 & 27 of Consumer Protection Act so file petition u/s 25 & 27 of act before Forum and get order of attechment of property and arrest of opposite party.

The consumer forum does not have to examine its own order.
