Oh yeah, I can understand that if the number was geographical or 0800 more people would ring it, but my problem with 123-reg is thus:
I have a .name domain (amongst many other domains I hold with them) and the only way I can make any changes to it is by unlocking the domain (like a .com or .org domain), making the changes, and locking the domain again.
I also have a .biz domain, which has the domain locking feature right there on the control panel. However, since I bought the .name domain, the domain locking ability is NOT there in my control panel - and after MANY heated emails and support tickets, I've been informed that they plan to put domain locking for .name domains there "in the future" but in the meantime, the only way I can make ANY changes to the domain is by ringing them up, getting them to log in to their tucows reseller account, unlock the domain whilst I'm on the phone, make my changes there and then whilst tech support on the phone waiting to relock it, and then instruct them to lock the domain again as soon as I'm done.
After 3 phone calls like this where I wanted to make the simplest of changes, I gave up out of frustration and ended up setting the domain up on FreeDNS (freedns.afraid.org) where I already have the DNS for quite a few of my domains hosted. That was very much a last resort though, as I wanted to use some of the included services 123-reg offer domain registrants
and now I've had to go work out an alternative.
I shouldn't have to pay to unlock/lock my own domain! It's their inaction in rolling out the feature which they offer for their other domains already which has brought me to this... And as I'm paying almost a third of that £120 just in domain renewal fees, they're definitely getting their money's worth out of me given that they buy domains in bulk at a vastly reduced rate from the Nominet per-domain fee.
(The moral of this story: DON'T BUY .NAME DOMAINS WITH 123-REG, try getting one via 1&1!)
