XxJAGERMASTERxX: Snap has given me the best support I've ever had with an isp. I've been with telecom and Vodafone beforehand and both seem to have international call centers (or employ people with very heavy accents) and don't help at all or i cant understand them.
I've been with snap coming up 3-4 months, have had a couple of hiccups but everything got sorted out fast and haven't looked back
Although you can get bad support fromr NZ based support people too. The benefits I have found with overseas based support, is that they seem to be available all hours (I think telecoms is 24 hour), and also there is often no waiting on hold. Which with NZ support can be a problem. I was on hold with my bank for 30 minutes, and they have a NZ based call centre.
I haven't had any problems understanding telecoms support people, and often it seems to be answered by people with NZ accents anyway.
