SLS Spring Woods: Maintenance charges are a shocker.

SLS Spring Woods - I'm honestly so frustrated with the maintenance charges here. Jab property li thi, they promised ₹4.5/sqft, but now it's jumped to ₹6.5/sqft. This is for a 3BHK, so it's a significant jump for us. Amenities like the clubhouse and gym are barely maintained, but they expect premium rates. My current 2BHK in Marathahalli had better facilities for less. Is this common for completed projects in Bangalore? We're already managing a home loan and this extra cost is just too much. I'm looking to upgrade to a bigger place, maybe a villa, but this makes me doubt if the premium is ever justified. What did others do when societies suddenly hiked charges post-possession?
