A piece of duct tape (sticky side out) wrapped around a piece of foam on the end of the coat hanger might work. It would have to be wrapped with masking tape in such a way that only the distal end is sticky - or it may join the phone"s entombment.
On the other hand if Pradeep is an engineer (of any type), it may be time that he reduced theory to practice and got his hands dirty by removing the seat himself.
If the above does not work, drive over to my house. As I live in Costa Rica, I can guarantee a dislodgment before he gets here.
