If a regular customer care interaction does not solve your concern, Kotak Mahindra Bank offers a structured, three-level grievance redressal system. This framework helps you escalate unresolved issues step by step, from an online complaint to senior nodal officers.
Always keep your service reference number, copies of emails, SMS alerts, and any statements when escalating.
When you first raise an issue with Kotak Mahindra Bank, you start at Level 1, which covers most routine credit card complaints. This level is meant for quick clarification and resolution.
Here are the typical steps involved:
After submission, you receive a service reference number. Use this number to track status through Net Banking, the mobile app, or other support channels.
Alternative Channels:
Expected Timeline:
If your complaint is not resolved at Level 1 or you are unhappy with the response, you can escalate it to the Nodal Officer. Level 2 provides a more detailed review of your case.
You normally need to:
Nodal Officer Contact Details:
Expected Timeline:
The bank generally targets a resolution timeline of around two working days for Level 2 escalations.
If Level 2 does not resolve your concern, you can escalate the matter further to the Principal Nodal Officer at Level 3. This is the highest internal escalation point within Kotak Mahindra Bank before external forums.
For Level 3, you need to:
Principal Nodal Officer Contact Details:
If your concern still remains unresolved after this stage, you may consider approaching the Banking Ombudsman or other external avenues.
If your complaint is not resolved within one month, or you are not satisfied with the bank’s final reply, you can approach the RBI’s Banking Ombudsman.
Contact Details of the Central BO Office:
Carry your service reference number, copies of communication with Kotak Mahindra Bank, and any supporting proofs while raising a complaint with the Ombudsman.
If you do not get a timely reply from customer care, try not to panic. Begin by checking whether you have received any SMS, email, or app notifications about your complaint status.
Contact customer care again using a different channel, such as the mobile app, Net Banking inbox, or another helpline number.
Verify and record your existing service reference number; use it to follow up instead of raising multiple fresh complaints.
If there’s still no progress, escalate to the Nodal Officer (Level 2) and then to the Principal Nodal Officer (Level 3), sharing all previous correspondence.
If more than a month passes without a satisfactory resolution, approach the RBI’s CMS portal and keep all supporting documentation ready.
Maintaining clear records, including dates, times, screenshots, and call logs, strengthens your case during escalation or Ombudsman review.
