[Resolved]  HDFC Bank — fastag application

Address:

New Delhi, Delhi

I booked a fastag on hdfc fastag portal and paid rs. 500 through my credit card. I did not receive any confirmation even the web page went blank and nothing populated. However, on the previous screen, i had noted down the reference id hr[protected] which was visible while entering credit card details
For payment.
I tried calling the hdfc fastag helpline[protected] throughout the day but the number seems not working and the call doesn't go through saying "number you have dialled is busy".

Please help.
