How to request missing documents in a consumer court case?

In my medical negligence case before the Consumer Court against a hospital, the opposite parties have failed to provide several important documents in their response. How can I request those missing documents? Is there a specific format? Should it be a separate request or included in my evidence affidavit? As the next stage is for me to submit my evidence, can I state that I cannot submit evidence until the OPs provide the missing documents? Or should I proceed with my evidence and highlight the missing ones? Also, since their written statement contains incorrect statements, do I need to refute each one specifically in my evidence?
