We have been with Tetrabyte for well over 10 years and they have helped us grow from a local community charity to a country-wide service over many sites. Initially providing full IT support services and now our transition to VoIP service over all sites. Their fantastic and patient tech team deal with all eventualities especially with technophobic staff. Can't recommend them highly enough. Di Smith, Systems Administrator.
