Not receiving monthly bills

I have not received my invoice / statement from Vodacom for approximately 3 months now. I have sent several e-mails to customer care requesting that my bills be e-mailed to me but have not had a single response. Last time I tried using the Vodacom app to check my outstanding amount, the information was 'not available'. I literally have to wait for an sms stating that my account is in arrears by R... so that I can go and pay it. I receive numerous computer generated calls asking me to select a date to pay to avoid disconnection, I usually receive these calls AFTER I have paid. I have tried phoning Vodacom to sort this out but the last consultant told me that I answered my security questions incorrectly (puzzling since I definately no my ID, full name, residential address etc.) so she could not help me.<br> It is now the 14th of the month and I still do not have my bill which would have been generated on about 5 April. This has resulted in non payment and now disconnection. I would like my invoices for the last three months e-mailed to me in pdf format TODAY as I would like to pay the correct amount due on my bill and I would like my services reinstated TODAY.
