Fascia and gutter in place

Our fascia and guttering are being put on today! Yesterday we went out to have a look and discovered  the neighbours have been using our place to dump their rubbish! We found chop bones, half a watermelon, a shattered wine glass, used cooking oil and BBQ rubbish/paper towels. It's disgusting! We shouldn't have to knock on their door and ask them to dispose of their garbage correctly! Aldo we found they are dumping their ashes from a fire in our back corner! Straight under the fence!
