123-reg - size isn't everything

The website host and domain name seller 123-reg tells us today that they are "the biggest web host in the UK". But are they the most reliable? In my experience, they are certainly not good at actually answering questions to their support website, when you have queries about email delays. (That is to say, they reply but they don't answer the question!) Interestingly, they are part of Pipex, which has repeated email delays through their ownership of CIX Internet and cannot sort out queries about their broadband services.

Would be delighted to hear from anyone who shares the same frustration.
