I've had my 021 prepay Vodafone number for well over a decade and am very attached to it. About two years ago I got the same number with a Telecom 027 prefix (only switched due to work circumstances). During this I kept my 021 prepay account topped up to ensure I kept the 021 number.
I last used my phone on 1 June 2009.
I turned it on again yesterday, 9 June 2009 to find it had been disconnected because the 365 day validity period had expired.
The Vodafone website says 'We'll TXT you to remind you if you need to make a top up, so you'll have plenty of notice.' (http://www.vodafone.co.nz/plans/prepay/topping-up.jsp). I did not get such a TXT. We've talked to several people at Vodafone regarding this, including the PA to the CEO, the Complaints Manager, and the Head of Complaints.
They say that if the phone is switched off or out of range they stop trying after 72 hours. However, I could not find that information on the website and it is not in the T&Cs (http://www.vodafone.co.nz/about/legal-stuff/Standard-Prepay-TCs.pdf). And we didn't know this, nor could we reasonably be expected to know this.
Apart from my complaint, I think that most customers would not know this. Effectively this means that if you go to parts of New Zealand without cellular coverage or travel overseas without roaming you *will* miss messages. I think Vodafone has a duty to tell its customers exactly this.
I asked Vodafone to reconnect. The Head of Complaints, who is acting with the full knowledge and authority of the CEO has checked with Vodafone lawyers and has flatly refused.
