Complete breakdown in communication

I set up new internet service for my new home to be activated around October 4th. The current homeowners still occupy our soon to be home. For whatever reason, Xfinity shipped out the new equipment to the new address without warning and without my authorization. I called the Xfinity number to get through to an agent, which was not easy, when I got the notification of the pending delivery. They said they would redeliver the equipment to my current address tomorrow. The new equipment still ended up getting delivered to the new address today while the current homeowners still occupy it. To describe my frustration would mean to use some choice four letter words that I'm refraining from using as of right now. How in god's name could Xfinity allow this to happen? How or why would they deliver equipment when I do not live there as of yet? Why does it have to be so difficult to communicate to a living, breathing, and intelligent human being in this company? This was a huge failure, and Xfinity is completely at fault for this disaster. I never authorized delivery for today and now I don't even know if Xfinity truly knows what has happened. You need living, breathing human beings to communicate with. You can't streamline everything and people don't want to talk to robots.
