Double billed in Dec 2015. my phones barred.

My phones have been suspended due to non-payment. Their accounts dept. fault. I was double billed in December 2015. I have been trying to sort this problem out since February 2016. Had feedback via email but still no satisfaction or reply from accounts or collection dept. Sent all the necessary documentation to lubabalo kwane at [URL Removed] as suggested by call centre. Vodacom outlets in Shelly Beach branch and South Coast Mall sent copies of our receipts of correct monthly payments.<br> My phones have once again been suspended. Don't know what else to do.<br> Thank you.
