DLF Moulsari Enclave: Post-possession snag list reality

Just got possession of my flat in DLF Moulsari Enclave last month, aur abhi se bahut pareshaan hoon. Builder ne jo promises kiye the, brochure mein sab kuch mast lag raha tha, but actual delivery... yaar, it's a different story. Snag list banate banate thak gaya main. Walls mein cracks dikh rahe hain already, bathrooms mein fittings loose hain. Kitchen counter top bhi uneven hai, tiles bhi kahin kahin hollow sound kar rahe hain. Matlab, this is a premium project, right? Maintenance team bhi bahut slow hai response mein. Jo amenities dikhaye the, like the grand clubhouse, uska bhi abhi tak pura kaam nahi hua. Is this normal? Has anyone else faced such construction quality issues right after moving in? Kya karein ab, koi advice?
