2 TV's - 3 Receiver Charges: Genie + 2 Wireless Genie

We had two ancient receiver boxes that stopped working and reluctantly made the call.  The tech installed a vertical style Genie box and a Wireless Genie Mini on TV1 and a Wireless Genie Mini on TV2.  We were told the Genie box was the "brain."  We are now being charged monthly for 3 receivers.  The first tv is "free" so the bill reflects charges for two receivers.  But only two tv's are hooked up.  CS says - this is how it is done? Is this really how it is done?
