Charged but couldn't find

We got changed for the Mike Tison fight last month but we didn't watch it cause we couldn't find it on our tv after ordering it. We tried for over a hour and kept going back to our phone and it kept asking for us to pay so we thought it didn't charge us. Today it is showing up on our bill? I don't think we should have to pay for it when we was unable to watch it. Also is there a number to call someone I can't find a number any where I had issues finding this. Thanks.
