Plot refund from Developer

In June 2020, IPAN Real Estate Pvt. Ltd. came with a advertisement that they are planning Suraksha Enclave Township ( SET) for Paramilitary Armed Force personnel, ABSAY (Akhil Bhartiya Awaas Yojna) around India at different location. So we approached them for Greater Noida Location. They conducted site visit in December 2020 and we visited the site. we participated in their Plot allotment draw and we were assigned one plot. All calls and Emails information were done through IPAN Real Estate Pvt. Ltd. They said that to book your plot I have to pay 10% and 15% in 60 days to Malaxminarayan Infradevelopers Private Limited (Developer) as they will be our developer. So paid in 5,90,150 in cheque to Malaxminarayan Infradevelopers Private Limited. For remaining 75% we opted for Bank loan. IPAN said that they will assign one bank ASAP and the township will be ready within 2 years verbally. we waited almost 18 months for bank loan from there end. Later I decided to CANCEL my registration. I contacted IPAN to cancel and refund my amount in AUGUST 2022. They said it will take 60 days to get refund from developer. its been 8 months with no response from IPAN and developer to my refunds. they ignore my calls and emails. I have buyer buildere aggrement on 100 rupee stamp paper. They aid the loaction is not RERA registered but approved from YEIDA local authority. What should i do? Do I need to go to NCLT or consumer forum or RERA? I,m confused and lot on mental agony.
