New Pune flats: Amenities are a bait-and-switch.

Just moved into My Home Sanctuary Phase I last month. The brochure promised a lot, but honestly, many amenities aren't fully delivered or are barely usable. Already seeing some minor plaster cracks and fitting issues in the bathrooms, which is frustrating for a new place. Maintenance charges seem quite high for the actual service quality we're getting. Is this a common experience in Pune, or is it just my project? What was your experience with promised amenities vs. what actually delivered? Any tips on tackling these construction quality issues?
