Yes I saw. The Advertising Authority South Africa made a ruling that stated that Prices may not be advertised excluding Vat any more as it confused some of the general public (AKA those that can't do maths).
Leave as is but if you do get a call from them you now know why.
I think they targeted Incredible Connection and Vodacom, with that ruling. I personally think that soon we might have a rule that the advertised price must include all admin charges as well, as you still see billboards that have *excludes R180 activation fee in them.
But you aren't the likes of Vodacom or Incredible connection so they might not waist their time.
