Nope. With other registrars where I haven't been able to update it myself, it's just been a case of a quick e-mail asking them to do it, and it's been done. I sent this lot a quick e-mail, and they replied immediately, telling me I needed to complete their form, which required everything from my full postal address to their billing ID number. I did that and so far I have "Your Ticket has been received and a member of our staff will review it and reply accordingly."
That link is for changing registrant - I knew there was a £10 fee for that.
Somehow, I doubt this lot will be so obliging. I have another site with them, on the same hosting package. (Both sites/domains actually belong to local non-profits, rather than to me.) The hosting packages state "free domain name for the duration of the hosting" - yes, I know there's no such thing as a free domain - but on the other account, the domain was invoiced along with the hosting. Unfortunately, I was ill at the time and they'd paid the invoice before I discovered the error. I contacted the company and they refused to refund the domain charges - said if we'd contacted them before the invoice was paid, they'd have amended it, but as it had already been paid, they "couldn't" refund it.
Well the first "mis-communication" would be when they told Nominet they weren't renewing the domain without communicating with the registrant. If Nominet hadn't e-mailed me, I wouldn't have known there was a problem.
I e-mailed the current registrar asking them to update the IP tag, so I would have thought it was clear that I'm changing registrars, not transferring the domain to another registrant.
