Nobroker — Need my money back but RM is not reachable

I had taken paid service (money back) from no broker. And for 1.5 months RM couldn’t get even a single tenant to visit my flat. Now I have got my tenant in my ow MN and have shared rental agreement with RM 4 days back. But no response from him. Trying to reach him but he is never available. Tried to call customer care many times but every time they say we have escalated and you will get a call back. It’s really frustrating and disappointing.
