Shubham Kumar — payment successful but pubg uc not delivered

Address:

Ambala, Haryana, 133104

Uc bought but not received
Purchased uc cash via in-app purchase of pubg mobile on 5 august 2019 at via internet banking. Costing rs.799 for uc credit of 660.

My account has been debited for the same amount but no uc cash was credited to the game. It shows in my SBI account that the money went in times of money limited.
Its a huge sum of money and i'm worried for the same.
Please refund my money to my bank account
