How to deal with noisy and dirty neighbours? Private rent, long term tenant. New tenants totally antisocial and filthy

Hi, I've lived in my flat private rent for over 22 years. No issues until last 6 years when flats on floor above me turned into buy to let and then the breaches of the lease has got out of control

I've stuck to the rules for over 20 years. Want to live in a clean environment and mind my own business and not disturb anyone else.

Been a load of renters directly above me for last 6 years causing a load of trouble, ignoring parking rules, having barking dogs when they aren't permitted, throwing rubbish about, playing loud music, shouting and just being nightmare neighbours.

New neighbours directly above. Constantly stamping on the floor with their dogs at all hours of the day, banging doors. DIY till 9 pm washing machine that vibrates through my whole flat in the early hours I'm constantly on edge. Woken up by them at 4.15 am today which is a regular occurrence stamping on the floor. Wrecking my enjoyment of my home.

In addition they have 2 staffie dogs which they don't walk - apart from round the property and outside my windows and urinate and defecate close to my windows. I can't open my windows because I smell their dogs waste and the grass and garden has been wrecked.

I've complained to my landlord and management company numerous times but they've done nothing.

These new people apparently own the property, but have been the noisiest and use the communal areas as a toilet. Worst neighbours ever.

Any advice as to how to deal with these people who are making me ill and what steps I can take?

Thanks in advance
