Gurgaon maintenance charges are a total scam

Been looking for a compact flat for almost a year now, kids have moved out, don't need such a big place anymore. Was considering Sector 95A for a 2BHK. Builders promise low maintenance in brochures, but I'm hearing stories about societies hiking them up ridiculously after possession. My budget for maintenance was ₹5-6k, not ₹10k+. Has anyone faced this in Sector 95A? What's the real scene with RWA charges there? Did you find any hidden costs after moving in? It's making me rethink buying.
