Don't think much has changed since Theresa Gattung's famous quote from 2006 - ""Think about pricing. What has every telco in the world done in the past? It's used confusion as its chief marketing tool." 😀
Spot on, although I'd like to hope that in this case it's just poor execution rather than a deliberate tactic. Compare to when Vodafone launched their endless data mobile plans and various promo offers associated with those - most of these were very clear, easy to understand, and upfront with pricing (refreshingly honest for the telco sector).
Unfortunately they haven't met the mark with this launch IMO.
Someone from Vodafone's NZ-based sales team is apparently going to look into this for me but it's not a great sign that even the NZ-based sales people don't just know the answer.
