Then the problem started when is time for the payment,that add price has changed. And in the past 2 month i spoke to an agent for cancelation of this dstv internet package and it seems like they don't want to cancel it,now i paid for this month service for my dstv pvr compact plus connection.my services to view is disconnected,they say the amount that i paid is for internet that i canceled 2 months ago.and they've charged me for cancelation. This month only my compact plus has been disconnected 3 times and they are charging me for reconnection.
