Explorer 3

Ever since I bought the explorer 3 on the 15th of August I couldn't enjoy the benefits. I tried calling dstv they have been sending me from pillar to post. I had to half day in order for me to take my decoder to one of their branches of which is too far from me. The hard drive of the decoder was ******* and they have changed my decoder but still can't use it. I have been for services that I didn't even use or enjoy. I want my refund. What the use of paying for explorer services? What happened to value for money? Dstv have been ripping us off. In future your decoder must be quality assured before been dispatched.
