redeem apple funds in india. Not apple to add card in apple wallet

So while purchasing an app subscription by mistakely i have added funds in my apple account.

im trying to redeem it but i need to use a gift card or code to purchase/ redeem the amount. And for that i need to add cards in my wallet. But im unable to do so because its showing “look for add to wallet button on apps” because its not available in India.

so can anyone tell me how can I redeem/ use my apple funds.

thanks
