Why must I replace the batteries?
The last time my security system notified me that new batteries were needed, and that I had to buy and install them,I called Xfinity and the rep laughed a little and said, "No, no. We would never ask you to buy and install batteries."
Also, a link was sent to my email, saying I could buy the batteries by following it. It led to a page that did not load. As usual, the chat function because it has not functioned for a few years.
Do I have to buy and install batteries or not?
