Bad Service from DSTV and staff that attended to my call

I was called by DSTV that they are running a promotion to get new DSTV explora 3b on price lock, after the first month I had issues with the explora had to take it to one of the walk-in center's had to take my device for more than 3 times

Yesterday my device shows E30 error and they wanted me to go back to walk in center again and after they told me that my signal and cable is faulty, I need to get a technician to replace the cable at my cost . when they were doing the initial install they did not replace the cable. now all my cost and they cannot locate they technician they sent to my house to do the install. to think that I am paying +R700 for this poor service and the call center agent Yandisa Njegele was refusing to put me through to a manager saying the all went out on lunch. I regret taking this service and also on price lock... DSTV has no care for their clients ...
