Still waiting for the bill breakdown

I have been a Cell C client for close to 8 years now and this month I have the received the highest bill in my contract thus far.<br> <br> Shocked by the amount (50% of which was for data), I called Cell C contact centre to get the breakdown or a detailed bill - especially showing me the usage of the data. It is over 7 days since I made this request - I am still waiting. <br> <br> As much as I have been a loyal client to Cell C and have always ensured that I pay my bill timeously, I am seriously considering to not renew my contract when its up for renewal. I have been hearing FNB adverts about their cellular offerings, I will probably make that switch....especially noting that Cell C does not have the courtesy to keep their word of providing a detailed statement.
