pip mobility

i recently had the assessment for pip and after having the high rate of mobility for 2 years and the use of a car my mobility was declined on points, I was awarded 2 points them mandatory reconsideration agreed with that so i went to appeal stage, i then got a 2nd reconsideration increasing my mobility points to 10, my mobility car was taken off me on 9th april, previously i had submitted a letter from my gp stating that i needed a car but i dont think this had even been read, then 2 weeks ago i was called to see my gp to be told that my acute breathlessness was diagnosed as a leaking heart valve, they have now recieved this, is there any way i can hurry this up now ?
