Pathetic service and quality of goods

We exchanged our \old PVR decoder\" for the explora at Ariel and satellite Pretoria in August 2015 to use as the primary decoder, this was done on my Mothers account (Yvette v Rijswijk). We then wanted to connect our HD PVR decoder as the secondary decoder so we got a DSTV accredited installer to do the set up for us. The installer could not do the installation and said the HD PVR decoder was faulty and we should take the decoder in to Ariel and Satellite
