pathetic service!

I had my dstv installed in 2011. They put one decoder in the room and one in the lounge for -599.00. I have been paying for one premium package since then. On the 7th jan 2015 i get an error msg on the tv in room i call the contact centre and they hook me up on xtraview(does anyone know what that means?) So now i go to pay my 665.00 thats due on sat 30jan and all of the sudden i need to pay 807,50 why? Beacuse i requested xtra view. So they say we will query it and contact you monday 2 feb so wed 4feb i call and they say you requested it. So i need to pay the 807,50 and by the way we disconnecting you for not paying for jan and u need to pay extra to reconnect it? Now is that great service for you! Yet all i wanted was to watch dstv in the room. And why havent they charged me for extra view in the room since 2011? Then contact centre agent drops the call in my ear with no resolution.
