Faulty Billing,Bad service & unsatisfied experienc

Bought an Explora on 23/11/2015. Was delivered to me on 25/11/2015 after I paid them R149 to get the ball rolling. I contact our Multichoice agency(Kuruman), they told me they do not do installtions anymore although they're listed by Multichoice. Phoned Multichoice customer services on the 26th they directed me to their field service department. They told me that they will let the installer they have phone me back to set up a date. On the 27th I phoned them again to tell them that no one has phoned me & that I have been without DSTV for a almost a week because previous PVR had a Faulty Hard Drive. They told me the installer can help me only on Saturday/ Sunday. After we had words, we agreed on Sunday. The installer did the installation & left. On Monday I phoned Multichoice again to complain that Box Office & Catch up is not working. Told me will take 72 hours to download. Phoned Wednesday night again to tell them it still is not working.They deducted 2 months' subscrition. Phoned on Friday & Saturday again & fixed installation myself, because the signal quality was not good enough & the advisors knowledge to help not good. No Catchup Still & no Refund received. Total calls 1h55min
