failed to update my ITC record as Closed or Paid

I did a premature cancellation 2014 march or so. Vodacom never updated my ITC records. I have called them several times and the last time I made a phone call I was told that by the 15 April 2015 the update will reflect on my ITC, but still nothing has happened.<br> It's amazing how quick they are to update your ITC when you are in arrears!!! Yet when they need to updated your ITC account status to closed they need to be chased behind.
