Matthew from Little Big Tech has come to my rescue on many occasions over the years. Booking a time slot is quick and easy. Today he sorted out a few issues with my work laptop really quickly in his helpful and cheerful manner. Thanks Matt
Lauren Ottewell's Review Sourced from Google
Thank you to John W at Little Big Tech who helped resolved an issue I had at work today. My query was handled quickly and efficiently and all communication with John was friendly from start to finish. Great service, thank you so much.
Karen Woodbridge's Review Sourced from Google
Little Big Tech have supported out business for about 4 years now and the team have always been super efficient and responsive. However they have just exceeded themselves even further. My emails were hacked and the LBT instantly stepped in to resolve the matter. Matt and John were on the case before I even knew I had a problem. They sorted the problem, isolated my system and drafted an update I could send to my clients to reassure them the situation had been managed effectively and there was no GDPR breach.I can't thank them enough. I was massively stressed and worried but I had the supermen IT team on my side.I can't recommend them enough.Thanks everyone.
