Our clients say...

Cannot recommend this company highly enough. Matthew talked me through an IT issue I was having patiently and professionally and all was corrected within just a few minutes. I am a total technophobe so was worried I wouldn't understand what I was being told, I was totally wrong. Clear, precise and in terms even I understood. Would definately use this company again. Five star service.

39D IT Support is so useful for me in my everyday life running a small business. I can call any time to ask for help with my computer systems and someone knowledgeable will answer politely and efficiently. Their service, in my opinion, is second to none. John

We've been using 39D for IT Support for 2.5 years now and they've been absolutely brilliant. They do everything from setting up new equipment, troubleshooting an issue, or offering advice on the best solutions for my business and they're always professional and reliable. Would definitely recommend them to anyone looking for solid IT support.

Since 39d changed our phones over our experience has been a lot better, easier access to the phone book from my pc as well as the phone. Easy to store numbers in a click. Pick up and transfer are much easier too.the whole service is a lot better than it was before. Not forgetting the staff are helpful and efficient and polite at all times ????

Matthew and his team have been solving our problems here at Rainbow Estate Agents successfully for the past 5 years or so. No reason to complain and happy to recommend
Alex Smith
This company goes above and beyond to support its clients. Being one of them i have never experienced a more robust support when it comes to IT infrastructure. The advice they give is honest and trustworthy and the speed in which they deliver the ongoing support is amazing. I would highly recommend anyone who is not happy with their current arrangements to contact the team at 39D. If you are yet to invest in protecting your businesses online presence, then make this company your first point of contact.

We have just moved to 39D and I have been VERY impressed with the service we are receiving. Considering we had a huge data merge to undertake they have been patient, quick and very knowledgeable. In particular Matthew, Jake and Chloe have been extremely helpful. We are looking forward to their continued service and expertise.

Having a major breakdown on sending and receiving emails. Which is a clearly a problem when running your own business. Also with numerous issues with my IT, I finally decided to try 39d. I was a little apprehensive - I had paid two different companies to try and rectify my problems. Within a morning my emails and IT had been resolved I have now signed up to D39. I can�t tell you how relieved to know that should I have a problem I just have to call D39 and they are there at the end of the phone. Matthew explains in terms I can understand. Highly recommended.
