Web Africa cannot fix Detailed Usage Breakdown

I reported the same problem twice. My problem is as follows: Under WebAfrica's Internet Access screen I have always been able to draw a report from their Detailed Usage Breakdown that gave me the data usage per phone number in an Excel Spreadsheet. Since beginning of August it is no longer so. Kabelo Theko responded via email and after much too and fro-ing, UmarBenjamin gave me a reply on 21st of August and then again on the 23rd of August saying that this has been logged by the developers. Nothing was heard since. I reported the problem again on the 4th of September to Ndivhudzanni Simali. He promised to phone me back. Only when I gave him a bad review in Web Africa's Rate our Service did he call back to say that the developers have stopped doing the Detailed Usage Breakdown. This sounded like an escape attempt. I asked to speak to his manager. He said his manager was busy and she would phone me the next day. I am still waiting.
