Poor service delivery.

I called dstv multiple times complaining about an E16-4 error ive been recieving ever since i purchased the new ultra decoder, the explora has been showing this error for two weeks. I called and spoke to a lady named Thoko for 40 minutes with my own airtime for nothing, the problem is still not resolved. So why dont you come and fetch your useless ultra decoder and stop advertising it, the service i got was so sloppy and unprofessional please fix this issue or i'll be forced to just use WIFI and stream content online. By the way DSTV im still waiting for my so called "escalated" call, i am close cancelling my contract.
