Balaji Group's pre-launch offers are misleading

Was supposed to finalize our 3BHK by last month, but this Balaji Group pre-launch scheme has me second-guessing everything. Initial pricing near 150 Feet Ring Road seemed great for my kids. But now, hidden charges like maintenance and PLC are pushing the 3BHK total cost way up. Did others face this with Balaji Group in Rajkot? Is this common practice?
