REALLY BAD!

On 21 December 2017 I was given a decoder bought on the special package MultiChioce is offering. R599 includes dish & installation. Since then I have called Multichoice three times trying to get an installer who will actually install. Each time I am given names, but either the number no longer exists or the phone is not answered or the installer will not install as he will only attend to call outs. On Monday I was told they would get back to me within 24 hours – it is now over 48 hours and no one has bothered. Why do they have an offer which cannot be fulfilled and why are they so inefficient that they do not have an updated list of reliable installers? Must I return the decoder and ask for the money back?
