Review Returns due to their empty promises

Bought a DStv Decoder with installation and after it arrived there was no info on installing. Called to ask what was going on and was told they would get back to me. 24 hours later still nothing. Called again and was promised they would call me back and still nothing. Got fed up and told them I wanted to return the decoder. They collected the return and then declined my refund because they said it was Multichoice problem to replace defective equipment. The return was not for defective equipment but for defective staff. Still waiting.
