Bad service

I phoned on 16 January querying my account for data bundles. The lady confirmed that I paid for a 1 GIG data bundle the 29 of December but it was never loaded. So I paid for the 1 GIG and was charged extra for data used. I requested an audit with this issue and it was lodged. S3-8UW20-09KYI - they stated it would take 7 working days, we are now at day 10 and have not received any feedback, or has it been rectified since and my account is again charged in January for data used but was supposed to still have left over from the 1 GIG bought on the 29 December. Vodacom is just steeling your money and never comes back to you!
