Poor Pathetic disgusting service

Very pathetic customer service. I purchased a DSTV 9s decoder with installation today a week ago and I was told to call Makro Crown mines for the installer. I did just that and they said the voucher is inside the box with the number to call the installer. I double checked there's no voucher inside. I callef again the first guy said he's in the wrong department he doesn't know how to put me through to the correct one, I hung up and callef again the girl pretended not to hear me until she heard me speaking about call avoidance than suddenly she can hear me and instantly transferred the call to a manager after being rude denying that she could hear me. The manager said they will get soneone from DSTV to contact me back and nobody did. I sent an email ro custoner service which they showed no cate at all and the best answer was if I wanna return the decoder I should go hand it in myself at Makro. I'm very angry and dissapointed at Makro, for a big company, you guys are so disgusting.
