ESA support group success and a quick question.

I filled in my transfer from incapacity benefit to ESA form about 6 months ago and got my answer this Monday.
ESA support group with no medical.
Thanks to the guides here I included a lot more of how my daily life is affected.
So, a big thank you and well done.

Now the question,
At the bottom of my ESA letter it states "You have been placed in the support group because your illness or disability restricts the possibility of working" it goes on to say I don't have to take part in any work related activity and I can see a personal adviser if I wish to do so.

This morning I got a letter from jobcentre +, they have demanded I go for a work focused interview to discuss work related activities, followed by threats of sanctions if I fail to do so.
Seems to me they have their wires crossed.
I have every intention of going to the interview rather than phone them but I'm not sure if I have to go along with anything they insist on me doing.

Thanks for any advice.

Thanks for the help, Gordon.
I'll ring the DWP and the jobcentre and let you know how I get on.

I rang the ESA number and after a bit of explaining I convinced them I was in the support group and not WRAG.
I was then told to ring my personal adviser at the jobcentre which it seems you can't do anymore, I was then told by the main office they would email my local office and I would get a call back in 3 working hours which could be between now and 10 am tomorrow.

That's it so far, stay tuned for the next exciting installment.

Just had the call back and they've cancelled the appointment and told me I don't have to attend any job related stuff and I'm in the support group for three years.
It was due to their systems not being up to date.
All very amusing when you consider both letters originate from jobcentre+.
Hope this helps someone else.

Thanks again for the advice.
