"ROI Technologies have been SARTA Recruitment's service provider for the last 10 years of the business. Absolute brilliant service delivery from Francois, Sonett and the Technical Team. Always proactive. Offer sound business advice and work on solutions."
Anna Maistry
MD, SARTA Recruitment · 10yr client
"Francois Van Dyke-Geyser and the team at ROI Technologies have provided exceptional IT support for my business. They have consistently ensured that our IT infrastructure remains secure, reliable, and running smoothly, giving me complete peace of mind. What truly impressed me was when they resolved a complex DMARC issue in less than 10 minutes — something my previous IT provider had been unable to fix correctly. Their technical expertise, responsiveness, and problem-solving ability are outstanding. Beyond their technical skills, ROI Technologies operates with strong core values, professionalism, and integrity. I trust Francois and his team completely with my IT needs and would highly recommend them to any business looking for a dependable and knowledgeable IT partner."
