Noida Extension builders: Post-possession quality ka kya haal hai?

Possession taken from Gaurs last month in Noida Extension, and honestly, I'm already seeing so many issues. Jab site visit kiya tha, sab perfect lag raha tha. Ab plaster cracks hain, kitchen counter top mein chips hain. Bathroom mein to seepage bhi dikh rahi hai already. Matlab, itni jaldi? I thought Gaurs ka quality track record accha hai. Mere ek dost ne ATS ka project liya hai thoda aage, Knowledge Park ke paas, usko koi major issues nahi aaye. Is it just my luck, ya Gaurs ki construction quality actually dip ho gayi hai? Ya ATS ka quality control better hai? What's your experience with these builders post-possession? Aur yeh maintenance team ko kitne calls karne padenge for these small things? Bilkul frustrate ho gaya hu.
