Device for upgrade

I upgraded my Cell C contact and orderd a Samsung S6 Edge device.<br> The device was delivered on Friday (04-02-2016) and was found faulty.<br> I phoned the customer care centre on Monday (08-02-2016) and they had it collected.<br> As I had no feedback from Cell C I made a call on Thursday (11-02-2016) and was informed that the replacement device has been approved.<br> The gentleman placed a order for the replacement device, I wanted to confirm the colour of the device but he said that the system did not allow him to specify a colour, but they will send me one of the devices in stock - no matter the colour.<br> When I had not received the replacement device by Tuesday (16-02-2016) I made another call and was informed that seeing as no colour was requested, the device was not released to be delivered.<br> I stated the colour I wanted and was told that the device would be delivered.<br> As of today (18-02-2016) I am still waiting for a device on my upgrade - 13 days down the line
