So I've had a pretty disastrous time with Vodafone lately. The usual customer service stuff for which they are renown for. Specific issue to be resolved was an incorrect bill.

Here's how I tried to resolve it:

Facebook Messenger: Some dialogue, but promised phone calls never came, even after one month

DM to official Vodafone rep on Geekzone: Some dialogue, but promised phone calls never came in the two week timeframe I was told to expect

Complaint on Vodafone website: Contact promised within two days, actual call back received (and issue resolved) within 40 minutes of clicking submit

So there you have it folks - go to https://www.vodafone.co.nz/contact/complaints/form/ for all your Vodafone issues, and standby for a call
