Runwal Group — Regarding possession and flexibility

I've booked my flat in runwal eirene project. Flat no 1903, T13. I've given almost 90% of the amount. Just 11 lakh is pending. Due to COVID crises I lost my job. Not able to pay pending 10% amount. So I requested sujata Rao ma'am to give us some flexibility. I've borrowed 5-7% amount from family . remaining I'll give them in installments or i can give them my parking for sell..so that amount could be adjusted but nobody is ready to listen from runwal group. We're from poor family but they are not ready to give us any solution. Please help us out ..or will push toward suicide only
