Thergaon property prices are a massive bait-and-switch

Just moved into my 2BHK in Thergaon last month, possession was in March. Honestly, the final price felt like a bait-and-switch from the initial quote. They added so many 'extra charges' and 'PLC' that weren't clearly disclosed upfront. My 78L flat ended up pushing 85L after registration, stamp duty, and all the society charges. Things nobody told me during booking! Is this normal for Pune, especially Thergaon projects? Did anyone else experience this with their builder here? What did you do?
