FamPay Support Hasn't Helped With My Wrong UPI Payment

On 25 July I mistakenly made a UPI payment of ₹500 by scanning a QR code through my Fampay (FamX wallet) account. The money went to a BharatPe merchant, which can be seen clearly in the attached payment receipt screenshot. This payment was done by mistake and I did not receive any goods or services in return. I want this wrong transaction to be reversed and the ₹500 to be refunded back to my Fampay wallet or my original source. I have tried to get help but I have not received any proper reply from Fampay support. I request you to urgently check this UPI transaction and help me get my ₹500 refunded as soon as possible.
