Supertech — no possession of apartment

Address:	E-Square, Plot No. C2, Sector - 96, Noida, Gautam Buddha Nagar, Uttar Pradesh – 201303, INDIA

I have booked a flat in supertech eco village 2 in greater noida west in year 2012.
Last year on discussion with mr. Vikas kansal (Director projects), he told me to take no dues certificate by paying all outstanding amount. Only after that they will start working in my flat and hand it over in next 3 months. I payed all payment in november 2019 and got no dues certificate.
Even after doing so, i am still waiting for my flat possession.
It is very unprofessional behaviour of the company and it's director that they are still fooling people and leaving no way of getting money from home buyers.
There must be a rule to stop all new sanctions of supertech projects till old projects finished as such companies collect money from one project and dump it in other.
Also to bring seriousness into this business, the owner of company shall be prosecuted and his properties shall be sealed till all projects finished.
We as buyers buy taking loans and for years paid interest to banks.
Kindly look into this matter.

Deepak
