Godrej Properties — flat purchased tower c unit 402

Hello Sir.
I have purchased a unit in Godrej Park Retreat Unit Tower C 402. When we went to their sales office in Sarjapur road the Sales team (Mohini and Saurav) mentioned there is plan (80: 20), where in the actual EMI will start post the possession of property.
We agreed to this plan and made an initial payment of 10% i.e 7 Lacs to book the flat in April 2022. We availed loan from Godrej Capital accordingly to the plan.
Our initial EMI from May 2022 till April 2024 was 8300/- Per Month (i.e 10% of loan amount). In April we received an email from Godrej Properties (Relation Manager Saket) they will initiate for 80% Demand and we need to pay by May 2024. He also mentioned the possession of property will in July End or by Aug. When contacted with Godrej Capital RM he mentioned basically the 80% demand will be raised 6 months prior to the possession of property. According the 80% loan amount was processed and payment was made to Godrej Properties by Godrej Capital.
Basically my Godrej Property RM does not answer the call, hence I Whatsapp to him today to check when will the possession of the property. He mentioned it's in December. If the possession is in December, then why the 80% demand raised in March. I am salaried women, and we stay in a rented house. I am paying 63700/- as the EMI to Godrej Capital + Rent of 17000/- towards the house. If we would receive the possession by Aug at least our rent would be saved. Now the Godrej Property team is telling it's in December we are paying actual EMI + Rent. This is quite stress-full, no one from Godrej Properties is addressing this issue. RM is not answering the call and Call center team is directing us to RM. We are having a difficult time due to their wrong commitments. After paying everything me and my husband is left with 2000/- to survive, nor Godrej Capital or Godrej Properties are unable to understand our situation.
We went ahead with Godrej Properties with the thought that they are committed to their words. But now it's totally other way around.
And the RM is not answering our call nor is anyone helping us or providing us with exact situation. We are reaching out to for your support and guidance.
