Ascent Buildtech — Flat possession

Address:	Ghaziabad, Uttar Pradesh, 201017
Website:	Incorrect information on Website. No valid contact no

After 2 years of follow up with builder, builder has sent us offer for possession.
After multiple visits to site, the construction is not yet complete. We have tried reaching ascent management.
They do not respond to it. Their sales manager are way too arrogant to help us on same.
We do not know whom should we approach for solution.
No one is responding. We have mailed them around 1000 times.
No response.

Seriously, worst builder ever.
