Whatever evidence you have against the opposite parties, you should give it to the consumer court / forum as per the procedure. Unless you give such evidence to the court, how will it know?
It happens in many cases that parties take time and delay the matter. But, beyond a limit, it would not be possible. If the opposite parties are delaying the case beyond a limit and do not appear before the court, you can request for an ex parte hearing of the case, i.e., hearing in the absence of the opposite parties if they fail to remain present in spite of being served.
