Missing Channels

This is the second time in a month that i am complaing about Starsat, i have been having issues with signal since i installed the HD decoder, i am paying for a full package but half of my channels cannot be viewed i was previously contacted by Starsat and given a reference number (TTP1588) for a technician in my area, made arrangements for him to come and check it out (1 October) he only came to me on 17 October he was arrogant and very rude, he did not even make an effort to see what is wrong all he told me was how much it will cost me for him to see what the root of the matter may be, i have had it now, so until the matter gets resolved i will not pay my subscription and just move over to the competitor, i am a very unsatisfied customer at the moment, PAYING R200 a month and only able to view half......should only be paying R100, and try call the call centre after hours what a waste of airtime
