STILL GETTING THE RUN AROUND

After several requests to have my invoices emailed to me, Vodacom is still not doing its job. it's the same old annoying response each time I call \WE HAVE LOGGED A REQUEST FOR YOU, AND YOU SHOULD START RECEIVING YOUR INVOICES. PLEASE CONFIRM YOUR ID NUMBER\". Nothing happens after that. It is extremely time consuming and frustrating having to call them each month to get something that they should be sending to me."
