@Lazar5 This is a community forum where hosts and guests can ask questions and exchange information. You would need to contact Airbnb directly for issues you are having trouble changing. And the things you want to change are easily done by the host, as Emiel has directed.
While I understand your frustration with the platform, as there are many issues for all of us, if you ever do need to contact Airbnb for help, they will not be very helpful if you start out by cussing them out. That's pretty much Human Relations 101.
