query not resolved after almost 4 weeks

I ordered a iphone 6s plus 3to4 weeks ago. .I confirmed telephonically with 2 agent's before the phone was delivered that it was the rose gold 6s plus. They delivered the iphone 6s. Which was sent back. I am disgusted in your service since the company is the one who messed up yet I am required to follow up and call. I demanded to speak to a manager on Monday 25 Jan and I was informed that there was no managers in the office as no one wanted to take responsibility to resolve the issue. Eventually the phone was cancelled and I had to start the application from scratch which the agent nonhlanhla did not send through. .I had to phone again and have the agents TL remind her to send off my application. She called me today to inform me that the previous contract was not cancelled and they can only approve the contract for R200. . I'm tired of being shoved around like this. I wan't this issue resolved. Here are my call ref numbers ***, ***, ***, ***. I suggest you train your call center agents soft skills as they have none!
