Bad service having a phone un-blacklisted

I run a company that purchases salvage and recovered cellphones from insurance underwriters and have purchased a recovered vodacom branded S6 from ABSA/Brolink. I took it in to the mall of the south Vodacom shop on the 27th of November and completed the required documents and provided the email from the underwriter requesting the item to be deleted from the IER/black list along with the clients name and the ITC reference number...the document stated that the unlisting generally takes 24hours and here we are 8 days down the line and I have not had any feedback or resolution of the issue. the consultant at Vodacom in mall of the south has been helpful to the extent that he can and has phoned me back when he promised to, but there has been NOTHING from the department that deals with this issue.
