[Resolved]  ICICI Bank — unlocking my debit card for online transactions

How do i unblock my debit card for online transactions from my registered mobile number?
My online transactions got blocked with a text saying - dear customer, due to security reasons, your icici bank debit card is blocked from 3d secure online trxn on 2901. For dtls, pl call customer care.
I was my mistake of having entered the ipin twice even after asking for an otp.
So when i call up the customer care numbers, after having entered the 16 digit debit card number, the recorded message repeatedly says that i only unblock the card from my registered mobile number, even though i'm the same number. I do not enough time to visit the nearest branch. Kindly let me know how do i resolve.

Appreciate early resolution
Thank you
