"Parasitical deposit..."

Held my deposit for 9 months after we moved out due to "cooker cleaning" and "damage" that wasn't explained. I refuted this and was ignored for 7 months, until I eventually threatened with legal and a campaign with Living Rent (Please join if you are a tenant to fight these **).
