All Digi-Sign systems and solutions are supported in accordance with our standard Service Level Agreement [SLA]. In accordance with the SLA support is provided on an escalated basis to ensure issue resolution in the shortest possible time. Unless otherwise specified, all support is provided by email or from the online Support Portal. Many customers also prefer to have telephone support and this is available at an additional charge on a 'per case' basis where 'support tickets' are purchased in advance. Alternatively, if you require unlimited annual telephone support this option is also available.
