Not a landlord, but I had a similar excuse thrown at me by a dealership. Towed my car an hour for a recall to a college town because everywhere else was booked for a while. They did close to $1000 of unauthorized work and then threw a fit when I told them I would not be paying for it unless they could show me a signed document where I agreed. When they realized I wasn’t a broke college kid after I threatened legal action and to report my car stolen if they were not willing to give it back, I got the “this was a misunderstanding, it never should have went this far” from the owner who had just called me a liar 10minutes prior. Such obvious BS
