Vodacom's inability to complete a simple task

I am so upset at how difficult it is to get a simple request done with Vodacom.I called in to the call centre to request an itemized billing to be sent to me last week a service request was logged and I was told to send a letter and copy of my ID through to have the service request actioned.I emailed these documents several times to [Email Removed] but just got error messages.I then contacted the call centre again and they gave me a fax number to fax these documents.I faxed them and kept the fax report but they have still not found my documents.A simple thing like requesting an itemized billing has now taken a whole week and I have gotten nowhere with them.I recieved a message to say an investigation was opened with the CIC department??An investigation for something so simple???Please just send me an itemized billing for the month of January!!!
