Gurgaon RERA complaints are mostly ineffective.

2 years delay on my Optus Abode project near Dwarka Expressway. I filed RERA complaints, but yaar, kuch ho nahi raha. Pehle builder ka legal track record theek se check karna chahiye tha. Ab lagta hai builder-buyer agreement ke clauses bhi sirf builder ko favour karte hain. Kya RERA Gurgaon mein bas paper pe effective hai?
