Spire World's maintenance charges are daylight robbery!

Honestly, I'm fed up with Spire World in Sector 98. Kids have moved out, so I'm downsizing. They promised low maintenance, but it's insane! ₹15,000 per month for a 2BHK? Is this normal? Resale se mil rahe paise toh maintenance mein hi chale jayenge. Anyone else facing this? Should I fight them?
