Call Centre Agents Not Assisting

<p>My problem started after I replced my old decoder with Single view HD decoder in April. Every now and then while I'm busy watching TV, my screen just goes blank for roughly 2 seconds. its so irritating when you busy watching your favorite programme. I have been to Multichoice Randburg 3 times everytime they give me a new decorder which doesnt resolve the problem. I changed the TV set but issue was not resolved. After suspecting the cables I decided to use the HDMI cable which also didn't resolve the problem. I NEVER HAD THIS ISSUE WHEN USING MY OLD DECODER.</p> <p>The last time I went to the customer care I did a survey to express how I was feeling but no one from Multichoice contacted me... Very poor customer service.</p>
