Evil property owner

Got a phone call today from the owner of the previous apartment we stayed in. Telling us there is damage to the flooring and we need to pay to get it fixed. Hmmm.... Why didn't the the real estate agent mention anything while inspecting the place when we left it? I don't remember seeing any serious damage. According to the owner the damage went through the protective wax layer on top of the flooring and damaged the actual wood. Hmmm.... Definitely don't remember anything like that. On top of that, there was no "current state of the property form" made when Kazumi moved in. So the owner can basically say what she wants. I really don't like this. I'm prepared to pay if it's not too expensive (just so we can forget about it and don't have to deal with this evil person anymore). But I would have to think twice before paying a big sum of money.
