Flipkart — Flipkart - Transaction was declined on basis the basis of risks check

Website: Flipkart.com

Hi Sir,

I am Harsh Yadav

I am Premium Customer of Flipkart, I am unable to make a purchase using any credit or debit card on my flipkart account. I have used all my cards on Flipkart many times before and my cards are working on all other online platforms, But on flipkart I am getting the message "Transaction was declined on the basis of risk checks" (see attached screen shot).
Please advise how to clear this, so that I can make payments as before.
as i want to purchase so many things.

I have subsequently received one standard response after another promising this issue will be resolved in 24 hours, 48 hours. It's now more than 48 hrs!! customer care has no resolution for this issue no one from the customer care team has any sensible information. Just the same standard responses. Seems impossible to get to someone who can resolve the problem.

Regards,
Harsh Yadav
