Greater Noida Authority — builder not obeying law

Address: Gautam Buddh Nagar, Uttar Pradesh

I got booked a flat of area 1075 sq ft in paramount emotions of builder paramount protocols ltd. My unit no. Is merry 202.
Now i am in need of money. So iwant to cancel my above mentioned booking.
I made a call to customer care of prpl. The official on phone line said me that company is not taking cancellation at this point of time
This is not acceptable as cancellation is my right and in builder buyer agreement it is mentioned that cancellation will be done after forfeiting 10% of amount. Being in great need of money i'm agree for this term also. But builder is unilaterally adamant for not cancelling unit.
Kindly force the builder to refund my money at the earliest and oblige.
Hoping an early reply
Thanking you,
Yours faithfully
