8000ZAR bill & NO response from Vodacom Business!

At the end of June I received a R10,000 bill from Vodacom (my average bill is R1800), of which ONLY R1200 is subsidised by my company! I have been trying in vain to establish what the reason for this extremely high data account was and to date I have had no joy from Vodacom, as well as being R8000 out of pocket.<br> <br> The chronology of events:<br> * Enquiry created by the Eastgate customer care centre assistant, Joshua Denyssen (extremely helpful and professional), on 16 July 2015
