DETAILED BILLING DISCONTINUED

I received my new statement and invoice, dated 15 April 2018, last month. I noticed that there was no detailed usage report included in the emailed tax invoice, as was previously done. I contacted Telkom via Facebook on 8 May 2018 and requested that they email me a detailed billing report for the amount of R73.23 billed under "usage - other operators". They rep**** -"we are unable to email detailed billing on previous accounts. You may register for online bill and view the usage via the following link https://apps.telkom.co.za/alpha/public/register." Why must I register for detailed billing again or view the usage on an app? Please email me the requested information and ensure that it is included with all future tax invoices! Is this so hard to do? Or to understand? I request senior management to intervene herein and resolve this matter urgently!
