Teen patti joy vip - Deposit not received in my game wallet

On February **th, I successfully made a payment of *,***.** to a gaming application named "Teen Patti Joy VIP." This payment was successfully received by their merchant and was even processed into their deposit account; however, they failed to credit this amount to my in-game account. They have been continuously making a fool of me and refusing to refund my money. For a full month, they subjected me to constant mental harassment by claiming that they had not received the funds; after a month had passed, they flatly reneged on their earlier stance, still insisting that they never received the payment—despite the fact that their own bank has explicitly confirmed that the payment was successfully credited to their account. Furthermore, they have also been persistently harassing my bank representatives, even though my bank had been in constant communication with them. Please help me recover my money from them.
