Complaining for my iPhone 6

Hi my name is Marcus Robert tlhomelang, I took my phone for repair at vodacom and for some reasons I haven't got it back because they say my IME number doesn't match with the insurance one and when I call them in cresta mall where I drop my phone to go to fourways repairs they says everything is fine with the matching and I've booked my phone more done twice which I never had a problem cause this is unexceptable and rediculars for someone who have been so loyal with vodacom for more than 10 years and I have to experience such, the question I ask myself is does it have to do with the color of my skin now "?... I fail to understand cause my phone has been there for more done two weeks which I use for business....may this please be taken to consideration and be dealt worth cause I am sick and tired of all of this...my job number is ***3 for my iPhone 6 ....very disappointed
