No Account for 7 Months!

I should be receiving my Vodacom Statements electronically. But the last time I received a statement was March 2015. I have to use the customer care line to find out the amount owed each month, but then there is no way to check what I have been billed for. I have phone customer care and spoke to a number of people after being sent from department to department (nobody seems to know who works with what!) and hours on the phone trying to sort out why I am not receiving statements, then the next month comes along and have to go through the whole process again!!!! Customer care has a long voice prompt and instructions and finally when you think you'll speak to a consultant, you get cut off to go through the voice prompted instructions again. Now they are saying I under paid on the last payment, but HOW am I supposed to know WHAT to pay. Vodacom, I have been a loyal customer for over 10 years... This is the last straw! I am through with you.
