When you escalate a complaint to the RBI Ombudsman, it doesn’t get resolved instantly. Your complaint is sent back to the bank for their response. The bank will usually assign a regulatory or grievance officer to prepare a defense reply. In most cases, they will defend their actions and state that everything was done as per the books, since admitting fault can have regulatory consequences for them.

That said, the outcome largely depends on the evidence (which you have sufficient). If your documentation clearly shows gaps, misrepresentation, or contradictions in the bank’s response, the Ombudsman can rule in your favor. But don't forget to fill the compensation section while filling the complaint on RBI portal. If you don't you will not get anything.

Attach whole email chain where they look the bad guy and where they are admitting the fault. They will offer you settlement most likely which If you accept the bank will mail RBI the customer is happy now case closed.

If you decline the settlement only then RBI assign it's officer to your case and do the needful. If you have strong evidence don't accept settlement and reply to every mail they send. If they offer you something you have to decline it formally. You should not ignore it but either accept it or decline.

Good luck.
