Can My Apartment Complex Restrict My Package Access Because Another Resident Falsely Accused Me Of Theft?

Location: Colorado. I’m 28F and I think my neighbor may have gotten me banned from the community mailroom by lying about me stealing packages. I live in a large apartment complex where all package deliveries go to one locked room near the leasing office. For the past two months, one woman in my building, probably late 50s, has had some weird issue with me ever since I asked her to stop leaving her grocery cart across the elevator doorway. She called me rude, said young women are always “looking for a fight,” and after that she started doing this fake sweet smile every time she saw me. Last week management emailed me saying I was no longer allowed to access the package room until further notice because another resident reported seeing me take “multiple parcels” that were not mine. I was completely confused. They would not tell me who accused me, but it was obvious. The only package I picked up that day was a dog food order with my name on it, and I have the pickup code email plus the delivery photo. Now they are making me come to the office during business hours for every package, which is a huge problem because I work hospital shifts and miss their window half the time. One important package with medication for my dog already got sent back because I could not get there in time. I asked if they checked the mailroom cameras before accusing me and they said they are “reviewing internal evidence” but would not say more. Yesterday that same neighbor smirked at me and said maybe this will teach me to “be more respectful in shared spaces.” Can management restrict my access to deliveries based on one resident’s claim without showing me any proof, and if this false accusation caused me actual loss, do I have any recorse against either the complex or the neighbor?
