Builder delays with CLP: what can we even do?

Construction-linked payment plans are a complete scam, honestly. ASK Developers ne toh meri life hell kar di hai. 3BHK liya tha Kakrola mein for my kids' school admission, ab 2 saal late ho gaya hai possession. EMI bhi jaa rahi hai, rent bhi. My wife is so upset, bolti hai ready-to-move hi lena chahiye tha. Anyone else stuck like this?
