[Resolved]  HDFC Bank — OTP not coming to my registered email id

Address: House number 0074D , Phulwaria road, Post Shivpuri new Colony,pin 273016

Website: hdfc net banking

I have to reset my net-banking pin. There are 2 options :

1) registered number + debit card — i can't use this because My debit card is expired 1 year before.(i don't have any new debit card yet)

2) registered number + e-mail : now the problem is 3 digit otp comes to the registered number but the email never arrives, i dunno why is it happening.

Ps: this used to work earlier, i have had reset my ipin by this method twice earlier.
