Hughes Net Cammy67 I Cancelled my service, and they decide the date to cancel when they are cancelling to they can keep my prepaid money. chicago Illinois

Hughes net bills in advance monthly.  I decided to cancel my service on March 6th.  My cylce is March 3rd to April 3rd.  I called to cancel and told them I'm taking down their dish as I have had the new provider install their dish.  This was done on the 6th of March.  Since they bill in advance and I paid for the entire 30 days I was expecting a refund. 

On March 9th I called again and asked why my account is still open?  The internet where I log on too, to check daily usage is still activated.  So I called and aske why?  Upon the phone call Hughes net will do a systems check. They say all is running fine and please hold for the next rep.  When the rep came on,  I asked why my account is still active. 

They said no it is cancelled effective the 6th.   I told him my account still shows active.  He assured me it wasn't.  I called a 9 days later asking where the box it to return my equipment is.  Upon this phone call,  Hughes new did a systems check and again said all is fine.  When I waited the 50 mins for the rep to come on I asked how can the systems check turn out fine when their dish is NOT installed? 

She said my account is cancelled and the "Standard Cancellation" is effective  the next billing period.  That means they keep my prepaid money for the remainder of the month!  I told her I get to decide when I cancel my account and not them.  I cancelled on the 6th, 3 days into the prepaid billing and I want a refund.

She said it is their policy to cancel on the next billing cycle to "Give me a chance to reactivate".  I told the rep on the 6th of March that I will not  be reactivating since the other provide is installed and up and running.  I had to actually fight with this person on the phone in order to get my refund.  How is this legall?  How can they put their "policy" over my request to cancel.  They must  be making a helluva a lot of money doing this!!
