Gurgaon property: M3M delays and zero support, common experience?

Okay I'll be honest — I completely underestimated how confusing this process is, especially with builders in Gurgaon. My M3M project on Golf Course Ext. Road was supposed to be delivered last December but abhi tak possession nahi mila. Builder ka customer support booking ke baad toh bilkul zero ho gaya hai. Phone uthate hi nahi. Sirf pre-booking mein sab bade-bade promises karte hain. Anyone else facing this with M3M or Godrej? Did you get any compensation for delays? Ya ye sab hidden charges mein adjust ho jayega?
