No Invoice Since October 2014

I have two contracts with Vodacom and used to get my monthly statement and invoices via email. The emails however stopped coming in October 2014. As a result I have had to phone to request invoices to be emailed to me. My email address has not changed. Every time that I asked someone to investigate why I am no longer getting the invoices automatically, they said a call would be logged and someone will get back to me. No-one ever did and I am still not getting invoices.<br> I visited Vodacom store at 5 Simmonds and asked them to look into it. I was told that I am better off calling the call centre, because their systems are extremely slow (which was the truth. Took them 35 minutes to get authorisation for a sim swap!!)<br> I would appreciate it if someone could investigate why I no longer get my statements automatically every month AND get back to me. I also need my Feb & March Statements.
