Hyderabad projects: unexpected costs after booking, what to do?

Lingampally — I'm looking at a Salarpuria Sattva project there. Honestly, I thought I had everything covered for my first home, but builder agreement mein kuch hidden charges nikal rahe hain. PLC charges, extra utility connection fees, maintenance deposit... I had no idea yeh sab itna add up hota hai. My budget was around ₹78L, but ab lag raha hai ₹85L tak jayega. Builders pe trust karna kitna mushkil hai yaar. Did anyone else face this with Salarpuria Sattva ya any other builder in Hyderabad? What did you do?
