Sharekhan Complaint Escalation Help

I have already taken my grievance against Sharekhan through the full escalation ladder—first before the NSE, then SEBI, and finally SAT. Each forum dismissed the matter on grounds of delay, even though I followed their timelines as closely as possible and gathered an extensive paper-trail to prove it. The effort, cost and time spent compiling emails, transaction statements and previous legal submissions have been substantial, and I am determined not to let the issue die only because the system keeps closing the file.

What I need now is a clear, actionable road-map that tells me:
• which judicial or quasi-judicial forum can still entertain the dispute despite the earlier “time-barred” rulings,
• how to frame the cause of action so limitation is no longer the sole ground for dismissal, and
• what fresh pleadings or affidavits should accompany any new petition.

Your deliverable will be a concise strategy brief (3–5 pages) that cites the relevant provisions of the Limitation Act, SEBI Act and applicable precedents, followed by a draft petition or representation template I can adapt for filing. If additional material from my existing dossier is required, just specify it and I will supply scanned copies immediately.

Accuracy of citations and practical, step-by-step guidance are the two acceptance criteria for this job.
