Incorrect delivery address

I have been waiting for the delivery of my device for over a week now, firstly when I had done my upgrade I put my personal number to be contacted on, and DSV contacts the contract number that I do not use. So then I had to wait for mtn to approve my personal number and the DSV people to contact me on my personal number, three days later they still did not and they kept calling me on the contract number that is not on me, yesterday I then contact DSV yet again only to find that my device is in Durban and I am in JHB and I had added my address when I was applying for the upgrade so I really do not understand how did it end up in DBN but I am really dissatisfied with the service from DSV at this point. Clearly, someone is very *********** and is inconveniencing me in all of this.
