P.O Box trouble, can someone please help???

My roommate has a P.O box and we are sharing it but we are technically not supposed to and I bought something but somehow it was sent under my name instead of my roommates because my name is on the account I ordered it on. I don’t want my roommate to get her P.O box taken away. What can I do? I already ordered two things.

the post office may send it back to the seller, as there is no one by that name associated with the po box. You need to contact the seller.

At least in the dorm you can share a PO box. You just need to inform them that you are sharing and you need to pay for it.
