From past few days i am not receiving any otp from bank for my online transactions. Even m not able login through netbanking as well. I shuttling between whitefield bank branch and customer care to get this resolved and this is not yet resolved.
Because of your irresponsibility i am facing lot of troubles transferring money to people and i have missed certain payment due dates. Neither bank whitefield branch or customer care.
Can you'll please take necessary steps and resolve this issue as soon as possible.
I have two accounts savings as well as current in your bank. Disposal of salaries to my staff depends on this otp. Please resolve the issue as soon as possible.
