123-reg in the UK never even responded to a query however fortunately I eventually worked out how to use their diabolical control panel.
I am glad its not just me!
Like many others I have never had a query on domain registration so I can't really comment on how good any of the companies that I have used are in that area.
If you plan to consolidate to double check what TLDs the company supports. If you have ccTLDs you will probably need to use registrars in the countries concerned.
