Dstv just don't care

A agent of dstv called me coz i was interested in the R499 dstv explora however i did the application and the dstv agent advised me that a credit check needs to be done however 2 days later the installer calls me saying his outside my house with my decoder and had i knew he was coming i wouldv made arrangements to be at home so i set up everything and i call dstv to activate the decoder and now they saying i must call the installer to come and install it before i can use it...i call the dstv contact centre on *** and they keep messing me around and i called again and the agent assured me she will assist me however the agent put me on hold for almost 30 mins i mean i work in a call centre u comeback to the customer and u advise them that u busy trying to get it sorted but i give up and i want a damn phone call back from a superior coz this is ridiculous and pathetic service
