Super appalled by DStv customer service

6th October I was called for my Price Lock application because I had app**** via SMS, the person I spoke to by Male of Tebogo told me that my decoder will be delivered and installed on the 14th of October, he even gave me a ref number #G551H1...come 14 October, I call the installer and to my surprise he tells me my decoder hasn't been delivered to his store, I lay a complaint via Twitter and Facebook but no one is willing to help instead they tell me to wait until the installer calls me...till date I haven't received anything..I'm super appalled by the service from Multichoice staff its super disgusting
