Should I pay No broker.com or Hire a Broker

Hello everyone, I am looking to rent a flat in Raymond's / Vartak Nagar / Pokhran Road areas. I tried NoBroker.com, they have a few owner based rental properties in these areas. However they are asking for 5000/- + GST to get Owner details. Other option is to do it via broker and pay him 1 month rent. But the issue with brokers is these days they sign a contract with owner and try to eat your deposit as well while leaving the flat giving one or other reason. What do you guys suggest? P.S: I need the flat on 30th March
