WFI though I am a carer

I've been put onto income-based ESA (WRAG) with the Carer's Premium as I care for my wife. I was asked to come to a work-focused interview. I read on B & W's ESA faq's that, “A partner who is undertaking significant long term caring responsibilities that make the prospect of work, paid or unpaid, unlikely at the present time may have their WFI deferred”. So I wrote in explaining my circumstances and asking for my WFI to be deferred. As I didn't get an answer I phoned the jobcentre put the same thing to them, but I was told that sorting out my issue was part of the purpose of the WFI and that I should go along to the interview. So I went, the lady was quite nice but in answer to my questions told me the WFI was mandatory, that she wouldn't refer me to the work programme this time and that she would see me again in two months. She also implied that eventually I would have to take part in some kind of work-related activity unless I could get myself into the support group.

So what can I do now? Complain that the jobcentre are ignoring the regulations concerning carers and work-related activities? Am I right in saying that the relevant regulations are the ESA (Work-related activity) regulations for 2011 para 3 (2)? And, since these regulations seem to excuse me from all work-related activity, why can't I ask for my WFI's to be waived altogether rather than merely deferred?

Thank you for that Gordon, I should have read the advice more carefully. I'm a bit confused though – I'm required to take part in the WFIs but not in the work-related activity. So what is the actual purpose of the WFIs in my case?
