Rain Billing issues

I have been trying to sort out my Rain billing for December so that I can get reconnected. For some reason the outstanding amount is showing a total that includes 2 months billing and not just the amount that was payable mid December. I have logged a ticket but no one has gotten back to us. Our ticket reference is #***8. All we want to do is pay the minimal outstanding amount (which should be around R1600) so that we can be reconnected. Please sort out our billing asap as we use the network for work.
