KS - management company cancelled my pre move-out walkthrough

I have rented a house for three years that is managed by a huge, nationwide company. My lease ends 6/14/26.

On 5/14 I submitted a request for a pre move-out walkthrough, and they scheduled it for 6/12.

Last Friday, 6/5, I received a notification that the walkthrough was rescheduled for 6/5 (that same day) so I immediately reached out and let them know that I could not be there and that I needed it to be rescheduled. They said that would be fine and someone would reach out. Nobody reached out.

On Tuesday, 6/09 I received a notification that the walkthrough had been completely cancelled and would not be rescheduled. I called them and was assured that it was done in error and the walkthrough would be scheduled and that someone would reach out. Nobody reached out.

I gave them Wednesday 6/10 to get it scheduled but nobody reached out, so this morning (6/11) I followed up by chat and then by phone, and ended up spending most of the day being transferred in circles. The only answer I can get is that someone will reach out to schedule, but I have zero faith that it will happen and I don't know what to do at this point.

If they ghost me and do not schedule a walkthrough, what do I need to do to protect myself from bogus charges down the line? The house is in good shape and clean and I was not worried about the walkthrough, but now I'm worried that they will try to charge me for something made up and I won't have the proof from the walkthrough to back myself up. Also, are they legally obligated to do a walkthrough?
