xFi Pods

I am trying to purchace a pack of xFi Wifi extender pods online, but whenever I click "add to cart," it just sends me to a page that asks me to contact one of their "friendly and knowledgeable representatives." I have gotten no help whatsoever because I'm only getting replies from a messanger bot and it cannot comprehend my issue. I would just like to know why I cannot simply purchase this item. If anyone can help me, that would be wonderful.
