Pubg Mobile India — Money deducted but didn't got UC

I've recently purchased an UC on 15th July 2021 from an in-app purchase of 340₹ 40₹ was discounted by googleplay. So the issue is th amount got deducted from my account & in the application it showed payment failed. After that I tried to purchase it again by credit card & got successful the second time.
So I'm requesting you for a refund on my first (google pay) transaction.
