At VFS Mumbai if you opt for courier service it would be delivered to your home address if you dont take the courier service you have to go there asper the passport collection time and collect it providing a valid government id proof

I can understand what you are going through can only suggest stay strong and keep fighting if one mp doesnt respond visit another one but dont stop your fight email the pm office aswell
Hope things move ahead for you
