Still no handset after 27 days

So I am currently on holiday on an island, on Thursday the 24/03/2016, the day before I could leave, the wrong handset was delivered again, spoke to Maropeng from the call centre and was advised that everything was in order and the correct handset was on its way, received the delivery on the Thursday and guess what, they sent the wrong handset again, honestly don't know what to do anymore, I have hand enough with cell c, and will cancel this contract when I get back home, this is the worst experience ever and will not recommended cell c to anyone, why cant they just give me a rose gold iPhone 6s as I requested.
