Damaged hardware

This is poor customer service delivery.My dstv xplora was not 30 days old and broke. No dstv repersentive can't give an explanation on what happened. The decoder was exchanged at centurion branch. The second new decoder is broken again(dstv catch-up is not working) it's loading movies and series for the past 12 days. I'm paying R900 for this service and cannot get decent service. I would like dstv to cancel my explora contract and re-act irate my old hd per subscription that I had for more than 3 years without any problems. I will take this up with consumer council
