Poor Service and feedback

I submitted a phone for repairs under ADH on Monday the 28th March 2016. Was then informed that the phone is blacklisted. I was informed it was due to bad credit rating and that my phones guarantee under the adh expires on the 4th of April 2016. After phoning around I was able to find out that the bed credit rating was and error by Trans-union ITC and not Vodacom's fault. I then completed and submitted request for removing the blacklisting. I was told on the Friday the 1st April 2016 that the removal of the blacklisting has been approved yet it still shows as blacklisted on their system.I will be informed as soon as this has been done. This information was provided to me by Naheema. After not receiving any further feedback I went there today and was informed that the system still shows as blacklisted. I was then informed that the phone will not be fixed under ADH as the 2 year period is over. <br> <br> This problem is also preventing me from upgrading with vodacom
