ATS Triumph: Hidden maintenance costs after moving in

Moved into ATS Triumph six months ago, expecting a peaceful life after kids moved out. But yaar, ye maintenance charges ka bilkul samajh nahi aa raha. Brochure mein jo figures the, woh toh kuch aur hi the. Ab monthly bill dekh ke dimaag kharab ho jaata hai. Itna paisa deke bhi amenities ka proper upkeep nahi hai. Anyone else facing this issue? What did you do?
