Overhanging bushes/shivery Trees

I originally reported this on 21st July and the problem is worse now as the bushes/shrubs and trees from the garden of 35 Valentine Road overhang the pavement of St Swithins Road and continue to grow even further out with thorns and branches at head height. The people who live in the house have cleared the garden inside but have made no attempt to cut back the outside that is causing a major issue and making it near impossible now to walk on the footpath with out getting scratched or stuck on the bushes
