iiNet call centre staff are always friendly... but frankly I'd rather have someone rude who is technically competent. I've been an iiNet customer for over 10 years with no complaints, but then I decided to transfer to the NBN! The communication was terrible, my voip phone was cut off for a week without warning and then reconnected with the wrong number. My additional email address hosting, including my business address, were unavailable for close to a fortnight, with no explanation. I've lost count of how many times I had to call them, emails take days to get responded to. I got billed for modem equipment I was no longer using and for "additional email addresses" which were supposed to be included in the NBN plan. I did get all of these things credited back, but every time they stuff up I have to spend half an hour on the phone to one of their offshore call centres, where the staff are always polite, but usually not very effective. I thought Telstra were bad, but frankly iiNet are worse!
