The person at the front desk of where I live signed for it. So I believe my apartment is liable because it was under their responsibility until I sign and take possession from them. The manager is saying they provide a courtesy service to sign and hold our packages so he is not responsible. That is total BS...
Contact the property management company. I have had a huge list of issues with my apartment complex, most recently a stolen vehicle. No one seemed to care about our issues until I emailed everyone on their executive board. Repairs that I had been waiting on since April were done the next day and the regional director seems to be my new best friend.
Best of luck to you!
