Pubg — cash debited

Address:

New Delhi, New Delhi, Delhi, 110029

Purchased uc cash via in-app purchase of pubg mobile on 025/02/2019 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.

Customer care centres are unreachable..
Please refund my money or credit uc..
