Supertech Limited — delay in possession after paying 100 % money to supertech

Address: Dehradun, Uttarakhand

Sir
I have 100% paid amount for flat in ecovillage 1 greater noida flat no. B2, 705 unit.
I was promised to hand over flat 3 months back in 3rd may, 2018.
The date of physically handing over flat has been extended in arbitrary manner by company.
There is irresponsible behaviour and unprofessional approch.
Still i don't know when i was given possession after paying 100% payment.
Writing to crm team is useless as there main aim to bluffing the customer.
