Empty nester's maintenance charge shock in Bangalore

Maintenance charges in Bangalore projects are becoming a total scam, honestly. Kids have moved out, so we're looking to sell our big place and get a manageable 2BHK flat, maybe near Prestige City. But the amount builders quote for maintenance vs. what you actually get is shocking. We visited a project, they said ₹6/sqft, sounded okay initially. But then the amenities are barely used, security guards are always on their phones, and the common areas look just... okay. Matlab, it's not value for money at all. Is this normal everywhere now? My old house hardly cost this much to maintain. Does Prestige City have proper service for their high maintenance, ya phir sirf naam ka hai? Any advice on how to check service quality beforehand?
