Xfinity shipped flex box to my new apartment a month early, and I am unable to retrieve it

I am moving to a new apartment in another state at the beginning of next month, so I called Xfinity to handle the change of address. While on the phone, they asked me if I wanted to get the Xfinity Flex box, and I said yes, but told them specifically not to send it until after my move in date, since I won't have access to the new apartment until I move in. They said that was fine, and I double checked with them at the end and they said they would send it to my new apartment on February 2nd.

However after the call, I got an email saying it was already being shipped to the new apartment. This is a problem, because I don't have access to the new apartment since I'm out of state and not a resident there yet, so it will likely sit outside for a month and at possibly get lost or stolen. 

What is the best way to resolve this? Should I just wait a month and hope it's still there, and try to contact Xfinity at that point? I will try to contact the apartment in case there's anything they can do, but I don't want to be liable for this if it gets lost or stolen, since Xfinity sent it early when I explicitly told them not to multiple times.
