Double standards

I am unhappy with how the move in and move outs inspections are handled, they would literally just want you to sign a satisfactory move in inspection even though there are things you are not happy about and need fixed. The shower walls were filthy and disgusting and we were promised a cleaner that never came. How are you saying the apartment is ready when you haven't done a thorough check first before the tenants come in? Then when we do the move out inspection the curtains are now inspected, the same curtains that we found in a bad state so much that even the guy who washed carpets in the building couldn't wash clean! Then when it's time to go after a 2 month period these mold stains on the curtains are your fault? I'm beyond displeased!
