Flipkart — Payment screen showing "transaction declined due to risk checks"

I tried to place an order but it is only showing "transaction declined due to risk checks".
I made a new account on flipkart since the account i was using was linked to my old number which i don't have access to anymore for otp (changing email). On the new account I tried buying 2 gift cards with supercoins but was unable to pay the first two times because i was unsure and clicked on the wrong payment app the second time. I was able to buy them after 10 mins through gpay and it got credited in my account. Today, i tried to finalise my order but it won't work/accept the gift cards and only shows payment declined. I have already tried to pay 4 times today but only met with the same popup message and don't wish to try further incase my account gets suspended for suspicious activity. If my account has been falsely flagged i would like to get it unflagged manually by flipkart customer support and wish to resolve this issue within this week as i am trying to buy some important books i require.
