Paytm.com / Times Of Money — times of money ltd- money deducted but uc not received

On 27th september, I purchased uc in-game from pubg mobile and the money was deducted and transferred to times of money ltd but uc was not received.
It was worth 800rs for 660uc which I paid rs 724 for after using a google play credit reward of 75rs.
As the money is hard earned, i request you to please give me a refund or have the uc reflected in my game account.
