If what you say is accurate just provide them with the equipment return receipt dated June 27th. You did get a receipt didn't you or did you just hand it to some 18yr old kid at the front desk and left? If you read their terms they ALL say no pro-ration if you cancel. Exact same thing goes for all cell phone providers as well as DirecTV (who I used to work for) and Dish. 1 day into the month and you own it. Like renting. If you move out on the last day of the month but leave some property behind and pick it up on the 1st of the following month you (legally) owe for the month.

I save every equipment return receipt for at least 5 years. I learned that from working for DirecTV. They can ding you for non-return 3 years later (it has happened).
