Pdp Developers — Deceiving in plots

Address:

Gautam Buddh Nagar, Uttar Pradesh

I purchase the plots shown by harit dharaa on jaipur highway. After that, they show me a farmhouse on same jaipur highway as "buy back plan' saying i had to pay 2.40 lakhs and after 1.5 years they pay me 3.50 lakhs and i liked it. But, they said that agreement will be on 'pdp developers pvt ltd' name. I asked about it and they say it is their sister company.
I book that farmhouse on 2.4 lakhs and after 1.5 years, i asked about the money (I. E. 3.50 lakhs). They say pdp developers is no more their sister company and their owner now is mr. Mathur. I constantly calling that mr. Mathur since 2.5
Years about the money and he is saying he will give the money when he had.
I sum up the money by very difficulty and they cheat us like we are millionaire.
