What you have been told to check before:
Rules on dates of notice, access/changing locks/harassment.
You have not done yourself any favours at all by letting this subject roll out to their rules.
You could have lived peacefully, without abuse or harassment, safe in the knowledge that you have rights and they can't abuse them. Taught them a lesson in manners and humanity.
Go and see them at CAB and tell them everything that's happened, from the threats, the eviction and harassment.
It's probably too late to do anything now, but if you haven't already changed the locks, do it, as for them to force you to do anything (as i've said before) they'll have to take you to court, and you'll be long gone by then.
You need to be clear on leaving date, so that you can plan with the council what happens next.
You need to see then what options you have for maintenance, because you'll need it!
The CAB can help you with advice on all this. Time is pressing, and you are not informed.
Make a mistake here and you could pay badly for it.
You've been treated beyond abysmally, and it's not on. So please set this right and get yourself some control back.
