DSTV - USELESS

It is 4.35 p.m. and channel 132 is, ONCE AGAIN, not available. I watched for 5 minutes and then...... GONE, blank screen. I have reported this to DSTV on a few occasions, but needless to say, it makes no difference. What does their Technical Team do to prevent this from happening every second day???? Yes, increase the premiums, but we have to put up with pathetic programs and blank screens. If DSTV would like to respond, PHONE ME, don't answer PRIVATELY - I don't know what that means!!
