HDFC Bank — Email OTP never received in registered email for HDFC netbanking password reset

Hi,
My name is Nabajyoti, I am facing issue to reset my HDFC Netbanking password. I write to HDFC customer care but not getting any resolutions. Hence I am requesting to support me in this issue. I am facing serious trouble as currently I in abroad.

Issue: HDFC Netbanking password expire need to reset online.

HDFC provide below 2 options to reset netbanking password online.
1. OPT in registered mobile + debit card detail.
2. OTP in registered mobile + OTP in registered email.

I have to use option 2. I am getting OTP in phone but OTP in email never received.

I contact customer care in email they replied that my email is configured correctly. So problem is I received all promotional email and my statement in the same email from HDFC but not the OTP.

I need help on this issue as I am current in serious trouble and will need to reset password only with this method.

Appreciate your support .

Regards,
Nabajyoti
