Vampire, have you been in touch with your MP? When my Husband had to stop work 4 yrs ago, and this is a Man who has worked extremely hard, with no time off his whole working life. At the age of 60 after being ill and struggling on for a year, refusing my pleas to get him to see a Doctor, he finally went, almost dead on his feet
to the point where the Doctor's first words to him were " How the Bloody Hell have you kept going in that state?"
So...I digress, but I want to point out that my Husband is not and never has been a "Waster" So, to start with he is on the basic level of ESA, then he had to attend an " Examination" with ATOS I of course went with him for moral suppost and also as he is profoundly deaf since Birth, and I took notes which they didn't like too much. It was the most demeaning experience of our lives, and stressed DH out such alot.
Two days later I had a phonecall from DWP. A woman calling herself the decision maker...We have stopped your Husbands money as he scored NO points!! I asked her what she knew about Parkinson's, and she said ( I kid you not) " What is it" I almost exploded. I asked her how she could sleep at night, taking on the job of a so called decision maker when in reality all she had to do to qualify for her post was to be ablw to count to 15!!.
I then got straight onto the MP's office, the Lady there was Fantastic, she told me that although they couldn't get the DWP to alter a decision they could make them sit up and take notice, and also have them call me at a prearranged time. We then went to the GP, who is also very supportive, he wrote a stinking letter to the DWP. I set to at the same time and had a letter of appeal in the post the next day.
In the interim period I had occasion to ring DWP again, and the Guy was so obviously reading from a script. I told him to stop that right now and fetch me someone with half a brain. He said someone would call me tomorrow as he didnt want to talk to me anymore 
By this time the MP's input had gotten through as had the Docs letter and our appeal. I was called by a manager who was very civil, and pleasant. Within a week I had another call, they had changed their minds and were putting DH not only back on ESA, but in the support group. He said the money will be in the bank within a week. I said " No it won't, you will personally see to it that it goes todsy, faster payment"...you know what? it was in later that afternoon.
All I am saying is fight the good fight and don't let the bastards grind you down, make a nuisance of yourself, keep at it like a dog with a bone. The sad thing is though, and this makes me very angry is that most people in this situation are very ill, and not everyone has someone to fight on their behalf. That is so wrong.
Sorry rambled on a bit but once I got typing I couldn't stop !
