[Resolved]  Godrej Properties — godrej vihaa not giving input tax credit of gst charged

My name is sanjeev and have done booking of flat in godrej vihaa badlapur about 2 years back. Have been paying all demands coming at various stage of construction for my flat. And from last year 2017 july onward builder has started applying gst charges, but still till date builder has not given input tax credit.. I have been following with various person in godrej property by writing emails and calling them but still itc credit amount is not given and continue to charge gst.
I request for attention to get input tax credit on gst charged by builder.
