Multichoice is now MULTI PROMISE!

I took up an offer on an upgrade and price lock for another 24 Months, since my contract was over. They appointed an installer who never pitched up. This installer said the do not install any more since they not getting paid. I contacted Multichoice, holding on for 35 minutes. They promised to get back to me. After a week they came back to me with a SMS. The same installer. I thought they were paid and they will come to Install. Still the same reply. I contacted Multichoice again. They said on there CHAT that the matter was escalated and an agent will call me. It is now more than a Month with still no installation. End of the Month I see I was now billed for TWO premium package. They said they will fix it but I do not believe them any more. I tried to call, after holdings the line for 45 min I backed off....EISH what now. Where to now.??
