Equipment Deliveries to a unoccupied summer home.

This a reqular problem. Comcast refuses to deliver equipement to any address other than your service address. We have a family home on the Jersey shore but it's seasonal. Our full time residence is outside of the Xfinity service area, 2.5+ hours away. At 6:11PM on the day that I had just closed the house for the season I received an email that I was being sent a new something, (router/modem/cable box) that had to be replaced by Oct 25 due to an encryption issue. Little did I know that it was being shipped the SAME DAY. Once I received notice that UPS was delivering it one day later, I contacted that wonderful chat support gang. After going through multiple agents, telling them no one would be at the address to accept and secure whatever they were sending I was assured that the shipment had been cancelled, which I seriously doubtful of. And, of course, that didn't happen, The delivery is on the front stoop, exposed to the weather. 

 If Comcast is smart enough to know that I subscribe to a seasonal plan during the winter, why can't they figure out I might be somewhere other than where they want to send me something, practically unannounced.
