Don't buy Dstv decoders with vouchers, service suckes

I have bought a Dstv dicoder from Deon Cresta on Friday 23 of Feb 2018, I redeemed the vouture on sutaday morning 24 Feb 2018 by calling Ellies, they allocated an installer which never bothered to even call me, I called him and asked him when would he be able to come and install the decoder and he said on Sunday 12 noon which he never pitched , I called him at 14 30 then he told me that he will call me back which he never I then called him at 15 00 he told me he won't come because he doesn't have cables, I was ****ed off , I went to Deon and told the about the poor service of Ellies. If I knew I wouldn't even bother buying the decoder since whether you like it or not you have to use the service of Ellies because all voucher are redeemed to them. What an inconvenience, my decoder is still not installed.
