I'm currently on long term sick, 10 months with "moderate-severe mental health issues" - Oh assists words. OH assist wrote to me asking for permission to ask my GP for details on my health conditions, I replied to the letter the same week it landed. They also sent a letter to me arranging a phone interview on the same day the interview was scheduled, at this time I was in hospital so I missed the interview. They are saying I've not responded to the permission letter in the time period specified, and obviously that I failed to attend the ridiculously short notice telephone interview. I'm beginning to feel they are playing dirty in an attempt to stitch me up.
How should I proceed with this?
Edit: Also my parent is currently terminally ill, and I'm having to deal with all her care (as her sole carer) and financial affairs, she has been extremely unwell in recent week and I have been spending most of my time in hospital so in any case I feel there have been mitigating circumstances at work.
Thanks for any advice
