Received a package from Xfinity addressed to my home but with someone else's name on it

Last week I received an email about a cancelation request that I did not make. I logged into my account to confirm, and it appeared to be the case. Luckily, I was able to get this resolved through virtual chat. Today, I received a package in the mail from xfinity with someone else's name. I'm assuming this person tried setting up an account and entered the wrong address (I live in an apartment complex) and this triggered the cancelation of my account. What's the best way to return this package, and does this person have any idea they've put in the wrong address? I wouldn't want this to keep happening.
