Not updating credit bureas with payment profile in

I took out a cellphone contract in a December 2014, Cell C advised the relevant credit bureas of the new account opened however has only sent profile payment information once in Feb 2015 confirming that my account is paid and in good standing. Why are you not sending regular updates to the credit bureas? Are you waiting for me to miss a payment so that you can send negative information about me. It seems like Cell C are just as self centered as other big companies on the market, only interested in ruining your credit record for the benefit of themselves. Please update my information with the relevant credit bureas, do I really need to ask you to do this on a monthly basis?
