Ats Infrastructure — delayed project and possession of apartment

Ats casa espana, sector 121 mohali, punjab.
1. Possession time for agreement done in 2013 and 2016 is same 42 months. This means for 3 years there is no progress on project and only money accumulated.
2. After 2 long years of repeated reminders on phone and email as well as repeated personal visits, finally a one line mail was received, showing a total callous attitude of the hired staff.
3. Possession date of apartments is extended by 6 months after every 6 months. Resulting in ripple effect - paying of more rent, child's schooling, job planning.
4. Leading to excessive stress due to totally an unplanned schedule and uncertainty of the project completion.
5. Small agreement compensation of ₹5/sq. Ft/month doesn't even cover the rent part. It was initially proposed that ats has not paid this delayed compensation as they always finish projects before time.
