Flipkart blocked my account

It had a gift card balance which I bought,i still have the gift card can it be redeemed in another account?

They blocked my account because I ordered a peel corn they deliver the whole corn for 20rs they blocked my 10 years old account

What can I do to unblock my account

I will not use flipkart again in my life again but i still need to recover that gift card balance if possible
