dstv voucher installation

i bought a dstv at game I was advised to call ********** 099 this number so i can have an installer come to do this was on the 12/08/2017 the y said it would take 2 to 3 days a installer will call me to set an appointment to day is the 21/08/2017 yet still no call from the installer or anybody showing up at my house to installer my dstv. I called in today again as usual I was put though from one person to the other and when I get to some one from Durban I presume they said they are putting me to the call centre and the phone just keeps ringing with no answer is this the service we getting for buying and installing a dstv it not like its for free i did paid for it and was given a voucher for it and im still going to pay to have access and watch these channels im so disappointed because it would be an easy solution buying it with the voucher but I guess I was wrong the service is appalling
