Well, after getting stuck in the no man's land, i tried to request indus for transferring it to my mother's name who's a filer. They simply denied it saying transfer of name not in policy. Then i was offered two options.
1. Submit extra 1 lac of non filer tax and get delivery.
2. Cancell booking, get refund and re apply in mother's name.
Option 2 seemed to involve couple of months so opted for option 1. Submitted PO to dealership today. It will take 2-3 days for indus to acknowledge it through NCS banking system. Then I'll get my delivery, meanwhile new invoice will be generated which I'll collect later.
So i think the lucky day would be around coming Tue or Wed.
