I understand your fustration. After a parade at MK a few months ago, while leaving the CMs stopped the crowd from moving forward with their ropes, so I stopped. The woman behind with a double stroller did not stop but repeatedly rammed the back of my legs with her stroller until I turned around & screamed at her to STOP! I'm not sure what she was trying to accomplish but there was no way I could move & I certainly wasn't going to let her continue to hit me. So while I doubt you have a legal leg to stand on with a complaint, I would advice to scream, it worked for me.
