How does investor grievance process work if you have an issue with broker

If someone has hands-on experience - and can share the steps … that would be great…

For example you have dispute about cash in your account …you think it should be more and brokers thinks its right …
what are the next steps ?
I think arbitration comes only after your initial complaint is not resolved through first NSE and next grievance panel correct? @siva @ShubhS9

I don’t have any issue …just want to learn …

Also how difficult it is to deal with govt. institution like NSE …same bureaucracy ?
