Data charged from airtime while active data bundle

I contacted Vodacom Customer care last week (June 24) to complain that the airtime on one of my contracts had been depleted without me using the number for anything that would use airtime.<br> <br> I was contacted by a very helpful lady who deduced that the number was being charged data usage against the airtime even though i had an active data bundle. This resulted in my airtime being depleted unnecessarily as the out of bundle data rates charged against my airtime depleted it quickly.<br> <br> I was informed that this matter would be taken up with the Advanced Data division in order to determine why i was incorrectly charged data rates against my airtime when i had an existing bundle active on the line. The expected turnaround time was 2-3 working days as per the email i received. Today, a week later, 5 working days later, i have not heard back from them as yet and to the best of my knowledge i have not been reimbursed for the airtime that was incorrectly billed.<br> <br> Quite pathetic service I must say.<br> <br> My reference number for this is: S3-8802I-IGDMS
