No real progress on a query

6 working days ago I logged an online query as the MyVodacom website no longer displayed my billing and past invoices. Since then I have sent further emails and the response that I receive is that the Online Support department is investigating, there has not been any progress with regards my query. Since data costs as really expensive I would very much like to be able to manage my accounts.<br> <br> Please just sort out my query.<br> <br> Thanks
