esa appeal

Hi
I recently won appeal for support group, after a year since assessment placed me in work group. Three days later I received a letter stating I had to go for WFI in a months time. I know that they can't force you to go for one of these if your in S.G. so I'm now worried that they may be planning to appeal the tribunals decision, as I haven't had anything in writing from them yet stating that I won appeal which was two weeks ago. Can you please advise. Thank you.

Thanks for prompt reply. I recently heard that they have recruited 86 DWP officers to attend appeals to try and appeal the decision made to the upper tribunal. A DWP member was at my appeal, which is why I am a bit worried and the letter to attend WFI arrived days after and it was to see a different adviser than my usual one, who agreed that Interviews could be conducted via phone call. It seems too much of a coincidence, to receive this letter days after my appeal and wouldn't the officer have informed them that I had won the appeal seeing as she was there? I'm probably being paranoid, but they have caused me a year of stress and anxiety, with the lies they have told. Thank you.

I did tell my adviser at jobcentre that I was appealing and he said he would inform them that I was appealing and have never heard from them since. That was last year. Is it usual for them to swap your work adviser? Thanks for your help.
