Vangis consistently demonstrate that they are efficient, professional, personable and that they work to the highest standards. Kevin and the team can be fully relyed upon even at short notice to perform the requisite install/remedial or site visits and its that level of service which keeps us coming back on all AV requirements. They advise us as to where we could make savings and they take a genuine interest in supporting our business. I cannot recommend them highly enough. I wish all our suppliers were as attentive, proactive and thoughtful.
