I have a client who we administer a .nz domain on their behalf, which they transferred from a web host about a year ago. We sent them a domain renewal reminder a few months ago which they paid, and we renewed it. However they have told us that their old provider also charged them for the domain renewal and their old provider had been sending them domain renewal reminders. They paid them without really think about it, and now don't know what they should do.

I have also had some of my own.nz domains which I had registered with a low cost domain provider (not the same one reffered to above), but after they raised their fees, I transferred them to another registrar. They too continued to send me domain renewal reminders. Their excuse when I asked them why they were sending them, was that their system couldn't detect that the domain had transferred.

How normal is this? Is it something that the DNC should be looking at?
