Nobroker — Rent payment

My payment reference number is NRP[protected].. I have made the payment on 1st June 2022. They have asked for the agreement to upload. I have uploaded the same. Still the payment is not credited to the owner. When I checked with them they said that they need some time to validate the agreement. I have requested them to cancel the payment since it was delayed. They neither refunded nor credited the payment of rs. 20000/-
