Builder claims about quality are mostly marketing fluff

₹1.2 Cr for a 3BHK in Future Aviana, and I'm honestly starting to regret it. Moved in 6 months ago, and we're already seeing hairline cracks, bathroom fittings feel super flimsy, and one of the balcony drains gets clogged constantly. The brochure showed high-end stuff, but the actual quality is just... not there. My parents keep saying 'buy only ready-to-move', and I should've listened. This affects everything, from potential resale value to attracting good tenants. Are these initial quality issues common or did I just get unlucky? What did you guys do about poor construction after possession? Does it even get fixed properly?
