Website:	Consumer Complaints

Dear Sir,
I would like to inform you that, i have booked a flat at PARK ELITE FLOORS sect-75 Faridabad. Haryana in the year of Oct.2009,
Till date i paid 75% of the payment and there is no construction activity at site only up to Brick work 50% completed and work has been completly stoped. no activity and no further demand for CLP.
Today on 9/11/2016 i received a demand for ZVAT TAX for an amount of Rs, 29, 745/-.
Please let me know what is this ZVAT? and how it will be applicable? on what amount and for which period.
Just this is they are harassing the customer without any construction activity.
