Bamatech delay, EMI pain! What to do?

Bamatech Realtors & Developers ne toh ruladiya. Possession delayed by almost a year now. EMI bhi jaa rahi hai aur ghar bhi nahi mila. Sector 102 mein phase hue hain. Should I just sell at a loss? Anyone else facing this? Kya legal action lena chahiye? I'm so frustrated.
