Supertech — hill town

I have been following up with below mentioned person in supertech for my hill town project :- mr gl khera, mr ak jain, mr girish gulla, all of three holding director ship in company. They have committed to me for refund of my pre emi payment and stop the future emi from indiabulls untill possession. But nothing has happened as of now. They have been harassing me since 2 and half month specially ak jain he is very cunning and cheater guy who has blocked my number and even didn’t pick any call where as he is the project head of supertech hill town
