ICICI Bank — Updating International Mobile Number

Address:

Vadodara, Gujarat

I am an ICICI customer for the last 7 plus years and I moved to the US about 2 years ago, I cannot access my online banking or pay my bills because i cannot access my online account without the OTP number. My Indian mobile number is updated in ICICI but no longer exists. I need to update my US mobile number, but i cannot do this online and talking to customer care has not helped at all. Its depressing to see that customers at international locations were not thought of when implementing OTP. Ridicule is, I can't even email to ICICI Bank Customer Care, through their 'so-called' website. It asks to login to my account, which is not possible without an OTP. Please somebody help me to get my US phone number updated or suggest a way to go about getting it updated. Appreciate any help. Thanks
