Social housing

I’ve had issues with a neighbour for 3.5 years (cannabis, loud music and harassment).

my housing association refuse to move me or deal with the situation. They tell me I have to get moved by the councils homechoice. The council say this is the housing associations issue. The police wouldnt charge. The council are now doing a occupational therapist refferal for the housing issue.

Has anyone had any Luck with these situations or any advise?  This has made my autism really hard to cope with due to having no quiet safe home. 

it’s very expensive to move privately where I live, so I really need them to move me. 

thank you
