New flats in Noida Ext are a hidden cost trap

Possession for my flat in the Top Builders corridor, Sector 121, was just two months ago, and I'm already regretting it. The maintenance charges are insane, yaar. Brochure mein jo facilities dikhayi thi, unmein se half bhi functional nahi hai. Pool ka bola tha June tak ready hoga, ab bolte hai next year. Phir bhi full charges le rahe hain. Is this normal for new societies here? Matlab, hidden costs aur amenities ka delay kitna common hai? Koi solution hai ya bas adjust karna padega?
