Useless and pathetic service

I bought an Explora with Kalahari.com when they were still around. My PVR stopped working last week so I got my installer to connect the Explora. I then contacted DSTV call centre to link the new decoder to my name. To my surprise , I was informed this decoder is already linked to someone else. Brand new item I removed from the box, sent pictures to them as well showing this is a brand new item and that it could not have been linked as I only opened it recently. I was told I need to go back to the retailer where I bought it to assist. I explained the retailer no longer exist and was informed that they would not be able to assist. I want my services disconnected and my bank account refund ASAP. No ****ing way that I am paying for something I cannot view.
