Compliance review still on going after 5 months

Hello! I posted before giving all the horrible details of my experience with a compliance officer.
I sent them all the bank statements they requested. They lost these and I had to resend. Thought that would be it but I’m now being asked for more details about the same account (an ISA) I do not have.
I supplied a letter from the bank showing all the account numbers o have or have had with them.
Nope still not good enough, she wants statements which I am unable to provide as it’s not my account.

Things now get complicated, I have had to go to Ireland as my dad had a stroke and needs care. I’ll be here at least 8 weeks (I’m also waiting on being rehoused in the uk so could be longer)
I updated my journal to tell them I went to Ireland on March 13th and will be here for 8 weeks (minimum) I asked for my claim to be closed/suspended as I know my entitlement will end. I claim PIP too so I know I have to be back within 12 weeks. I recieved the following journal entry yesterday
“Hi Jane, the review has taken so long due to your mental health issues and your desire to involve your MP. Whilst the Department is sorry to here about your alleged Menatl health issues and your fathers ill health at this time I am not in a position to authorise ANY absence from the UK until such time as I have completed my review. For the same reasons your claim will not be stopped/suspended.
Once I am satisfied with the documentation you have submitted we will be in touch and you can at that point end your claim and leave the country.
Whilst this may be difficult for you to hear, it is a condition of receiving means tested benefits that you engage with the process and rules.”

The issue is I’m already in Ireland with my dad (his stroke was very bad and he had no one to help him once he was out of hospital)
Do I need to return to the UK? The compliance officer has threatens to have my passport cancelled (via a telephone call) if I try to, in her words “skip the country”

I have put in a formal complaint as has my MP but so far we have been ignored.

Should I return to the UK? I have some everything in they requested but she still wants statements from an account I don’t have.
I have severe mental health issues and this all started whilst I was in a psych ward and she was calling and messaging daily (my psychiatrist wrote to them detailing the effect this is having but this too was ignored)

Can anyone help? I’m struggling to care for my dad, look after my own mental health and now I’m terrified I won’t have a passport to come home?

Any advice would be much appreciated

Regards

Thanks. Unfortunately the appt I have with CAB is the quickest one I can get.
I’m not in the UK at present and obviously caring for my dad is taking up a lot of my time.
I was just concerned as the compliance officer stated she can have my passport cancelled which would leave me stuck in Ireland.

Thank you for your reply. I have managed to get through to my case manager at UC who cannot find any rules that say I cannot go abroad. He has agreed to suspend my claim to prevent any future overpayments occurring.
Do you know how long the dwp take to answer official complaints? Myself
And my MP both submitted complaints and have heard nothing.
Aside from the comment from the compliance officer stating “you have no reason to complain”
