ON AIR TV.. *****ulent charges!

how do you people get to R2100 overdue on my account when I never even used the device or the service!!! I told you to come fetch the device it's never even been opened! I WILL NOT PAY FOR SOMETHING I NEVER USED and I will dispute this with the credit bureau. I told you to cancel this but no u can't even respond. WHAT A HORRIBLE PLACE THIS IS and on top of that they can't even give you a breakdown of the "charges"
