DON'T GET WHAT I PAID FOR!

I have paid R1499 for 12 months recurring 2G data in May 2015. For the past week there has been 0 available and I thought it would be recharged in time. After enquiring last night I got a message telling me to dial *111# (I KNOW THAT!) for balance and I was told there is 2G available. After calling *111# I received an sms telling me I have 2G until 01.01.2016 - WHICH IS WRONG! I have the same deal on another device and it shows clearly on My Vodacom that it is a recurring 2G bundle but on this number it says \unfortunately nothing to view"?? I need this rectified immediately!"""
