Czar Mahira Homes 63A: Hidden charges are a nightmare

Just moved into Czar Mahira Homes 63A last month and honestly, I'm a bit shocked. Brochure mein jo total cost dikhayi thi, it's not matching up. Possession ke time pata chala there are so many hidden charges, especially for basic things like parking PLC jo pehle mention hi nahi kiya. Builder ne bataya nahi tha clearly. Maintenance charges bhi promised se higher hain, they're demanding ₹3.5/sqft now. Matlab, it's a significant jump. Anyone else in Czar Mahira Homes faced this? Kya kiya aapne?
