On Demand Charge I Did Not Purchase

We received a text saying thank you for your 19.99 purchase on a movie we did not buy. The charge was for The Addams Family 2 animated one. We don't watch animated movies. We went on a full circle. And no one helped us, they told us to call a number from bulk packages as we live in a complex. The person kept saying " clearly you did click on purchase, otherwise you would not have gotten the text." uhm, clearly we did not and that is why we are calling. We were not even home at the time of charge. The guy kept blaming us with an arrogant attitude and refusing to listen. There were 5 of us who witnessed us watching the tv and never clicked anywhere that say buy. Plus, the movie they said we bought was 14.99, not even 19.99. We told him it made no sense, no one clicked three buttons to go to the option and confirm the purchase and there are 5 people who know that. we weren't even watching xfinity. and he kept going about yes, we did. so rude. He was not there with us but said it was us. We went back on the main chat only for them to tell us to call the number again and disconnect the chat. This is not cool. We expect there is no charge on our account. We are never gonna watch that movie.
