I am an international student studying in New Zealand and I signed up with Orcon in 2011 as they offered month by month contract and I was willing to pay a premium (that they were charging) which I felt was reasonable for a non-contract internet service.
When you're a paying customer, things are handled slightly better. That is not to say there is no hick ups (I come from a country where such hick ups would cost you business straight away) but I suppose one must accept the circumstances considering that telecommunications is not the best in New Zealand.
Orcon failed repeatedly to remedy the issues. I terminated my service with Orcon by writing in via email and secured an agreement to end on the day I leave New Zealand after I finished my exams at the University.
Breach of Contract
1. Orcon disconnected my service against our contractual agreement (yes, it is a contract in legal definition and the representatives entered into it on behalf of the company) early, during my critical exam study period.
2. The representative promised to send a prepaid courier bag to return the modem I have loaned from them. No such courier bag came. I made arrangements with my landlord hat if such mail came, to notify me immediately.
Horrible after sales Service
3. They proceeded to bill me a month after the end of my contract a sum of about $250 claiming that I did not return the modem. I replied explaining the circumstances that I was not in NZ and I am unable to look through my belongings which were in storage. I offered in good faith to return the modem if we could arrange for the modem to be returned and I would trouble my friend to search for it. No reply was given.
I continued to file a few feedback tickets via their website but someone the other end played the "this issue has been resolved" card.
4. They threatened to list my debt with Baycorp earlier this year and I have to call them to re-explain the situation and we finally agreed verbally that the reason for the debt (obviously) was due to the modem and if I returned the modem the debt is forgiven. I took a picture of the modem and sent it in an email with a written understanding of the Telecomversation with the staff as a written record for legal precaution (that she is free to contest) as verbal agreements hold up poorly in a court of law.

This was attached in an email correspondence to indicate that I had an intent to return and I kept the chattel in good condition. This would have been totally avoided if they actually sent the prepaid courier bag in the first place. This time they did and I returned the modem accordingly.

5. For some Damnable reason, they emailed me today 16/7/2012 claiming that I did not reply to their correspondence and will list my debt with Baycorp if I do not pay immediately by today.
Conclusion
This whole disgusting saga (including much frustration at attempting to contact them and largely summarised case) shows the abysmmal management that Orcon has and the total disregard Orcon has for after-sales service. I have considered going back to Orcon for I received good service (by NZ standards) but after this, I do not think their "premium" price is worth anytime at all.
If I get a credit impairment (this can be international, resulting in inability to apply for jobs or any other tests etc.) as a result of this (takes up to 7 years at least in NZ to clear a bad credit rating) I'm prepared to sue them for damages. My advice to everyone is to avoid Orcon like the plague. There are better services to be had for the same amount of money paid.
PS: And obviously I decided to go public about this. Please please avoid ORCON. They are not worth the headache.
