Nobroker — no update on my refund of token amount after owner refused to give property.

Address: Bangalore

I had finalised a property and given the token amount of Rs.10000 to nobroker for the deal. But after I talked to the owner he refused take the to-let banner down after the token to nobroker and demanded money. After I said that I had given token to Nobroker he refused to acknowledge the deal. when asked for a refund they are delaying by saying will escalate and not calling back i have been calling, emailing them since 3 weeks now.
this is causing me a lot of inconvinience and the 30 days of refund they promised is also expiring.
please help
