Delayed possession of flat

I had booked flat with Builder and signed agreement in Jan, 2013, builder was supposed to deliver flat in 36+6 months (25. July, 2016), but still I am waiting for possession. Builder is telling me below reasons and saying, there is no penalty, because there is clause in agreement (please see below last paragraph). Late Receipt of EC and CTE: This delay of approx 7 months was beyond our control. NGT Bans : National Green Tribunal’s ban on construction in respect of Okhla Bird Sanctuary From April 2014 to September 2015 caused a delay in construction for 18 months. Labour Shortage caused by Demonetisation: We lost 6 months in spite of our best efforts to retain the labour even at higher cost. Material Shortage caused by GST : This disruption caused an effective loss of about 3 months. We further wish to refer to the clause C 1& 2 Force Majeure (FM) of the Allotment Agreement, whereby it is mutually agreed not to hold the Company responsible and liable for delay in performing any of its obligations if same is prevented, delayed or hindered by any reason/s which are beyond the control of the Company. At this time our first commitment is to finish the Project and offer possession for which we need support of our clients like always. Through all this we have solely focused on delivering a great home to you as promised. Currently the construction/finishing activities are in full swing. Due to above said Force Majeure circumstances and reasons beyond the control of the Company the expected date of possession your Unit is revised. The details shared herein are force majeure as per RERA and allotment; we will pay to penalty in line with the agreed allotment for any delay beyond force majeure .
