Standard Chartered - Unable to apply for credit card

[Heyyy]

I already hold Ultimate card and Smart card from Standard Chartered. I wanted to have EasyMyTrip card for flat discounts on EaseMyTrip. But since last 3 odd months, I am not able to apply. On selecting "Do you hold an existing Standard Chartered Bank credit card"? on their website, and click on "Proceed to Authenticate" button, it redirects me to a billdesk URL with an error message on that page.

Is this happening with you as well?

I have been chasing their customer card but they are simple skipping this by saying it a temporary error, link is not for SC website, blah blah.
