My son has given me permission to share this.
After a long hard fight (1yr) he has won a gruelling battle against ATOS, they lied on his medical even dismissed the doctors report, several months later his ESA was re instated without question.
The fight continued as DLA used the ESA's medical info supplied by ATOS and stopped his dla without notice, even the panel on the tribunal were disgusted and demanded ALL information that they had been supplied, WOW forwarded to the tribunal service.
I got a call from my son yesterday saying he had received letters from DWP, bless him he sounded so despondent, then he yelled down the phone "I've got it", he no longer has to attend his appeal in Oct, he's got all of his money re instated and back dated.
However down you get DONT GIVE UP.
