Amarpali Silicon City: My payment plan nightmare

Under-construction projects in Noida are a complete nightmare, especially with these payment plans. We bought into Amarpali Silicon City by Let's Make Home Buildtech, thinking early bird discount milega. Ab 2.5 saal ho gaye, possession ka koi sign nahi. EMI bhi jaa rahi hai, rent bhi de rahe hain. Kids ke school change ka tension alag hai. My wife is so stressed about the uncertainty. Is this common? Kya karein, should we switch to a ready-to-move property in Sector 150, even if it means paying more? Builder ka track record kya hai for others?
