Poor Service

I've upgraded my contract over the phone on the 24th of November 2017, and since I did it at around 08:00 am I was told it will take 3-4 business days to get my phone. Unfortunately today when I called them on day 5 they told me that my phone is at warehouse, meaning that had I not call them it was going to stick there for some time. They said told me unfortunately I won't be able to get my phone today on 5th day even though I was supposed to get it on the 29. The consultant told me there's nothing they can do about it. I mean how hard is it to take a phone from Midrand or Jozi to Tembisa? I called around 13:00 and at 14:30 got an SMS telling me that my phone was only handed to delivery company. It's such a poor service, especially since I was promised to get the phone in 3-4 business days and even on 5th day I still haven't got it.
