contact us today: 01954718076 askus@miscom.co.uk About Us. We are a small company based near Cambridge, UK that has for some years provided subsidised services to Church and charity organisations, trading as Mission Computers. As Mission Compleat we are now expanding our service to include more commercial work. We aim to provide a personal service and to live up to our name, not just finishing the jobs we are given but doing them to meet your high standards. Our size means we can handle small quantities and so give you the personal product you are looking for - something unique to you - in the most cost-efficient way. We can, of course, handle larger jobs too!
