Hello folks,
Ultimately I got the credit card. I gave the my friend's where the credit card was available instead of my hometown (aadhaar address).
After the video kyc it was pending for 4-5 days I think. Then suddenly a bank representative came for address verification at the friend's place. I was not there. But I told my friend to tell I stay there as a paying guest. Ultimately the representative aproved the address.
Hope this info helps someone.
