Runwal Group — Mis Sold possession date multiple times

Address:

runwal residency pvt ltd, dombivali east, Usarghar Thane 421201

I booked a flat in Runwal gardens Dombivili T1 -1703 and was mis informed about the Possesion date on 3 different occasions:
During Sales pitch was told possession will be by Aug 2022. I asked for something in writing he mentioned it will come via email and requested me to wait.
The welcome email came after 5 days and said RERA date Dec 2023 i was irritated with this wrong details and approached the site head who reassured me that i wil get possesion by Dec 2022 latest and Dec 2023 is just a 1 yr grace period RERA provides.
Next i get a email of draft agreement that said June 2024 and also said a grace period of additional 1 year will be applcable which will make it june 2025. I dont understand now which of the information is true.
The managers at sales team Swapnil Kale was least bothered to resolve my query and despite msging calling even visiting the runwal office they are not bothered to give correct information or address a customers query on priority. I have not yet registered the agreement and all i want is either a written confirmation that i will get possesion definitely by dec 2022 as initially promised or my money back of rs 990998 that i paid which is 10 percent of agreement value plus GST plus TDS not a penny less. I dont understand why people cant give clear and accurate information and such poor customer service i did not expect from Runwal
