ICICI Bank — One Time Password (OTP) feature does not allow any transaction

Address:

Mumbai City, Maharashtra

I have an old India-based mobile number registered with ICICI Bank; however, I have stopped using that mobile number. Now, I am out of India and am not able to perform any transactions on ICICI bank website as it keeps sending my OTP to the de-activated mobile number. The issue is I have a regular salary account so I won't get the OTP via email. Being out of India, I cannot visit any branch personally to get the mobile number updated in the bank's systems. Please help me raise this concern and I hope ICICI bank becomes more sensitive towards customer service and sensible to understand such genuine issues.
