Itemised billing

I logged a call with Vodacom for not being able to access my itemised billing. Call was logged a call on 28 Jan 2016 , which was closed on 3 Feb 2016 (without my knowledge) Apparently I was informed to send a copy of my ID and a letter stating that I want all my Itemised billing details from Dec 2015 - Jan 2016. Firstly I was not informed that Vodacom requires documentation from me, and secondly I need the billing information in .csv format to be able to claim work related calls. It is now beginning of April, still in I not able to download my itemised billing in .csv formation (or any other format for that matter) from the Vodacom website. A service that I pay for, but is not available to me!!!<br> <br> REF ***
