If you are not satisfied with the solution provided by the bank and would like to further enquire the matter, you can approach the Banking Ombudsman established by the Reserve Bank of India under the Banking Ombudsman Scheme, 2006. Each bank is required to display at its branch the details of the Banking Ombudsman under whose jurisdiction the branch falls. Complaints may be lodged with the respective Banking Ombudsman here.
You can only do this once you have tried to settle matters with the bank, and failed. If you file a case in Court, such as the Consumer Court, you cannot approach the Ombudsman while the case is going on.
If you are not satisfied with the decision of the Banking Ombudsman, you may approach the appellate authority against the Ombudsman’s decision – the Deputy Governor who is in charge of dealing with the implementation of the Banking Ombudsman Scheme, Reserve Bank of India. This appeal must be made within 30 days of the Ombudsman’s decision.
