Cell c and Courier IT BAD SERVICE

I did an upgrade 2 weeks ago, still waiting for my device, I received an SMS from Courier IT 2 days after my order advising delivery on that day. I waited the whole day, then at around 4pm the driver calls to confirm my delivery address and said he is on his way. At about 6pm I called him cause he still had not arrived, then he told me that he doesn't deliver to my area and was taking my package back to the office to be rerouted. The following day I received another SMS saying delivery wl on that day, I waited again still nothing. I went on the tracking portal on their website and found out that it was out for delivery since the previous day. I called Cell C and they advised that they will follow up with Courier IT, then I'll be advised buy them of what is happening. I waited for feedback, but nothing. I kept calling both companies and was sent from piller to post and given bad attitude by their agents. On Friday last week I called in again and was told my package was lost in a ******* yet no one cared to update me. The consultant I spoke to assured me delivery latest the next Monday. Monday came, nothing, then on Tuesday a driver calls me saying he's outside my residence to deliver, only to find out he was at the wrong address. Since then no feedback has been given. I have not received my device till today and this is not the first bad experience I have had with Courier IT, they are ****** and always claim that packages are lost, or drivers are hijacked. I have no idea why Cell C is using them. I have been with Cell C for as long as I can remember, but the level of bad service I have received this time around, is outrageous. They don't do follow ups, when u call in they tell you the follow ups department opens at 9 and u must call back then, instead of logging an issue for you and forwarding it to the relevant department. They don't even answer their customer services emails they just leave everything up to the client. I'm very angry and disappointed. My devise still has not been delivered to this day.
