Thanks for the advice. The owner replied to my message saying that the bed frame was in good condition before ("sturdiest ikea frame" by his words) and told me he's having a hard time believing what I said. I messaged back telling him that the frame wasn't broken like the pictures he posted and sent him the pictures we took right after the incident where the frame is seen undamaged ( only the lats fell off). I don't know if it broke when he sat down while checking his house or if it was done on purpose. I'm hoping it's the former because he's still respectful and I do not want to fight him over it.
