TLDR; experience of going over your plan on $19 is unnecessarily poor IMO. Too lazy to do anything about it/first-world problem.
So my $19 prepay plan ran out of data 2 days early (I pretty much only use data, dont text/call much) and I got a text message saying that I was out of data and my plan would renew on the night of 2/11, and that I could buy 300MB for $6.
No mention of facing potential charges or anything (which to be honest I should have anticipated...it's probably in some user agreement I signed next to how vodafone are going to molest me when I'm sleeping) so I was duly charged for whatever it was I was doing on my phone when I mistakenly thought I was on wifi at home.
It is not buckets of cash, I can easily afford it, I just wondered why the difference in price/MB considering there is no mention of 'un-billed' data like I see on my Orcon bill. I have trawled the VF website but cant find anything on it anywhere.
It also miffed me that I was prompted to pay $6 for an add-on and such a thing isn't automatically applied if I accumulate $6 of additional data (kind of how other pre pay systems tend to work...transport touch cards etc)...it just seems to me to be a punishment for going over that at no point encourages additional purchases. I had over $20 on my account prior to these charges and I was not warned that additional charges had taken me below the amount needed to renew my plan...yet another poor thing. so my plan was not renewed automatically and I very nearly started racking up more charges for texts. these all seem like very simple things to me which could have been avoided and have only resulted in a poor customer experience.
Oh well, rant over, I don't use my phone enough to require immediate change, but I am annoyed enough to rant about it online. the situation will no doubt alter my perception of vodafone NZ, if anything additional annoys me I will no doubt be changing. sigh.
