JustDial.com — Transfer of booking advance from client

On 9th jun i received a msg that rs 10000 has been paid through jd payment gateway and asked to upload invoice as it was a booking amount for the marriage on september 5 2020
Invoice couldn't be raised as there is chance of cancellation n it is only booking amount i raised this issue with them but did not receive any response so i uploaded receipt which was rejected then again i uploaded tax invoice which was also rejected either they should transfer the amount or refund it to the client they do nither just sitting on the money which is not theirs
