Bad service, 3 weeks later and no device

I upgraded my contract on the 26th of Nov with MTN direct. They phoned me confirmed everything amd said the phone will be delivered within 3 - 4 working days. After waiting almost two weeks I phoned mtn direct and asked them where my device was and got told it was delivered on the 4th but that I was not there to receive it, I asked why I was not told about the delivery date and why no one bothered to follow up with me and I got a ridiculous reply that oh we do not phone you before the time if it is a busineess adress ***?? Ok so you don't follow up either? For such a massive company that is incredibly pathetic. They then told me it would be here this past week, guess what still no device and it is now the 19th. Almost a month already. I went the mtn direct route because their stores are atrocious with horrible service and very rude staff. I guess you can't win with a company that has inefficient processes and **** service across the board.
