An absolutely atrocious company to deal with. I was moved to 123-reg after they purchased TSO-Host and was disappointed after my very first dealings with their customer service. So much so that I had decided to move to a different hosting company. That was just a few weeks ago. NOW, 123-reg is down and I'm completely unable to access any of my websites or e-mail, OR login to my 123-reg account, and because it's the weekend there's nobody their to help!
My advice is simple ... don't touch 123-reg with a barge-pole!
