Heres my reasoning:
Unlimited minutes Skinny to Skinny become 1000 min although fair use policy doesn't particularly state a maximum.
People on the Skinny Facebook page receive conflicting reports of how many combos you can purchase a week and how they work - also the website doesn't particularly give you that information. Also the same with regards to other add ons.
The websites useless.
No MMS operating.
They've missed the point that Kiwis want more Data and alot of Texts primarily (i think)
They cut the opening hours in the first day of their call centre to a lousy 9 - 5.30
Everything seems to be in testing stage.
Most stores don't yet have Skinny Handsets & Sim Cards in stock.
If they sort that all out they might be halfway there.
