Stuck on MVN Athens, need real experiences

Since January I've been shortlisting flats in Greater Noida. Fed up of renting, landlord raised rent again, ab bas equity build karni hai. I'm looking at MVN Athens by MVN Infrastructures, my budget is around ₹80L for a 2BHK. My main concern is their actual delivery track record. Brochure mein jo timelines dete hain, woh real hote hain ya bas marketing? Also, customer support ka experience kaisa hai after booking? Do they actually communicate during construction delays, ya bas silent ho jaate hain? And the amenities, swimming pool, gym, clubhouse, woh sab actual mein deliver hote hain ya sirf plan mein rehte hain? For end-users like me, living experience matters. Any actual residents there can share their experience? Hope this helps someone else too.
