Kya Sector 140A mein project delays ka scene itna common hai?

I'm currently in a 2BHK in Sector 78, thinking of upgrading to a 3BHK in 140A. Ek project dekha tha, but builder ne 1.5 saal delay kar diya hai already. Brochure mein completion date kuch aur thi, ab toh bas OC ka wait kar rahe hain. My current EMI chal rahi hai, aur yahan rent bhi dena pad raha hai. Yeh hidden charges alag se... builders bolte nahi pehle. Kya sab projects ka yahi haal hai? Is it worth the headache, ya wait karna chahiye?
