Vispa Broadband, it just works, all the time. After 5 years as a Vispa customer, I think I've had two problems. Both times customer support was quickly available by UK phoneline or e-mail, was friendly and not at all techno-babble. Just solved the problem for me. A good, personal service. Not the cheapest, but probably the best for reliability, support and advice.

I particularly like the fact that when a problem is reported, it is allocated to a named member of staff who I can e-mail or 'phone to discuse the solution.
