JSDC has been established for over 9 years and has supplied a professional service to over 1500 people in South Oxfordshire. We are very proud of this and would like to share some of our customer comments:

“For more than 5 years now my wife and I have used the expertise of JCSD Computer Services to resolve the non-routine crashes and problems that have occurred from time-to-time on our PC based home network. Originally the network was an essential part of our international commercial consultancy business but since our retirement it still remains in daily routine use supporting a variety of personal and domestic functions. The service provided JCSD has always been thorough and their explanation of problems and the proposed solution very clear and once resolved have remained fixed. Since their charges are also modest and appropriately documented I have no hesitation in recommending this organisation for home-based computer support and maintenance."
Chris, Thame


"JCSD provides a personal, knowledgeable service second to none. Hardware builds and modifications are reliable and prompt. Software problems are dealt with efficiently"
Rodney, Wallingford


"JCSD Computer Services have been providing me with Computer/PC support for over five years. I have always found them courteous, efficient and reliable and their technical ability and support has always been excellent. Furthermore, their charges are very reasonable and good value. Initially they sorted out my laptop which I brought with me when I retired from business. Later they advised on updating my PC. They then purchased my new PC for me, installed and transferred all software and memory and reorganized my whole system. I have been very happy with the prompt and efficient service they have always provided for me since. I have no hesitation in recommending JCSD without qualification."
Colin, Scotland (previously Cholsey)
