Still not working!!!!

I complained about my blackberry a couple of months ago. I got a quick response and my phone was 'sorted' after 3 days. When I collected my phone the lady told me that it is a very ****py phone and I should buy a new one. They did not replace my old phone. Now, a couple of weeks later my phone is doing the same as it was doing before I sent it in. I am sick and tired of Vodacom. After a profile review I qualified for a Samsung S6 which I upgraded to on Monday morning 07:55. I chased my order this morning because I was told my new phone will be delivered today and now no one knows what's going on. My order has not even been dispatched yet!!! ***!!! This needs to be sorted today please ! My order number is: U906254
