6 months in Ansal Aastha — builder's fixes are a joke

Ansal Aastha Mig Zone — 6 months ho gaye possession liye, but abhi tak bathroom fittings leak ho rahe hain aur wall cracks visible hain. Builder ko complain kiya, but they just do temporary fixes. Iska kya scene hai? Already in a 2BHK, thought upgrading to 3BHK Ansal Aastha would be better. Is this normal after 6 months?
