This happened about 9 months back. The neighbour next door painted his fence red which has dripped through into my (leaseholder) green fence. He initially looked and admitted fault, stating he would buy paint to cover it. I asked several times and still maintains he'll sort it. I left it for a bit but asked the other day and came up with the same shit. On calling the council today they said they cant do anything. I can see myself holding a grudge over it - I generally don't think its my responsibility to sort out. Any suggestions?
