Your big mistake was ordering a car, until a grant is fully approved and finalised (which it is not when you got sent this list) the grant becomes null and void.
you should of appealed, wrote to motability and been patient you might have had a argument with him expecting you to charge away from home with the argument who is going to look after my wife why I do this and are motability paying for these costly charging away from home which in some cases is more than fuel.
