I received another box at my house for someone not there

About a month ago I received an email that there was an order to cancel my order.  I called, and after having to fight with the automated system to talk with someone, I finally get a hold of a live person.  They verified it was me, confirmed I did not cancel and they removed the cancel order.  I get home the next day, and find a package from xfinity on my door step for someone that does not live at my house.  I took this in good faith to the xfinity store to return.

I get home today: I find another xfinity box on my door step, again for someone else who does not live at my address.

• Why do I keep getting packages at my house for someone that does not live there? 
• Should I be worried that for 2 times now I received equipment at my address I never ordered for a name of someone that has never lived at that address
• Why am I getting these all the time?
• From the first time, how did someone manage to put a cancel order in for my service when nothing was done to verify it was me?  When I call, they send me a text to verify it is me.
• What can be done to compensate me of always having to drive to the xinifty store and wait my turn to return equipment you should of never shipped to me?
• Seeing I am getting equipment shipped to me in someone else's name, would that put me or my current account at risk if they never pay?
• I can understand a mistake of shipping something one time,  but two times a very good explanation is expected of WHY.
