Help with canceling apple watch order and billing questions

Hi,

I ordered an apple watch through Xfinity today and was hoping to cancel the order before it ships out because I was going over the price breakdown and it wasn't worth it to me. 

Also, I keep hoping on xfinity chat assistant but no one can give me a straight answer to what my monthly bill charges are supposed to be for the first cycle (including activation fees) and then what it should look like after the first month. I believe I have the wrong internet plan/bundle under my internet bill.
