You could probably get a solicitor to take up your case if there is compensation possible on a no win no fee basis. If you are a leaseholder you will be paying for this in your service charge. But this could get a reaction.
Maybe speak to your local ward councillor, and local police liaison (local councillor will have the details)the anti social behaviour/crime might get the officer to contact the managing agents.
Are you a tenant or a leaseholder?
