I have come across Microtalk, (http://www.microtalk.co.uk) who claim "Microtalk UK Limited has over 15 years of industry experience and has quickly grown to become a major player in the world wide telecommunication market. " Their deals look good. However I have been unable to find other information about them. They do not appear on the comparisons on thinkbroadband.
Does anyone have any information about them? Are they genuine?
