Are any of these images familiar to you, does your landlord expect you to live in such a mess? I may be able to help you. I graduated in law with honours in 2007, and having had such problems with landlords and letting agencies in the past (those images are from a house I was expected to move in to), I offer pro bono advice in the fields of land, consumer, contract and personal injury.
Mail me here giving details of the property, your name - it will never be revealed to the landlord and all of the problems. Photographic evidence would be very useful.
