Basically I have the worst landlord in the world. Promises to fix things........ takes years if done at all. He promised last winter to insulate the loft. Still no joy. I also need his address for insurance purposes. I texted and rang him 4 weeks ago. No joy. Kept on every few days. No joy. Can't find him on facebook etc. Should I cancel the direct debit so that way he has to contact me?
