I rent an upstairs flat and the flat below is having work done to it, we share a small front garden and only they have access to the back garden. They have filled the front garden with rubbish, old furniture, bathroom fixtures and fixings to the point we can't get the bins out anymore for the bin men to take. They have also damaged the wifi box in the front garden and we can't get to the box to see the damage or how to fix it, we've been without wifi now for almost two weeks, I have asked them to move their stuff but they say I have to speak to their boss - who's number they conveniently don't have access to. (which I don't believe) Is there anything I can do to make them move their rubbish out of the garden?? On a more personal level I can hear them making fun of me for asking as well since they are obviously just below me which is quite intimidating. I'm a young woman and its hard for me to get the courage up to keep asking these middle aged men to get their act together - is there anything that I could say to them that will make them respond??
