CGM Medical support is NON EXISTING

I use CGM Medical's MedEDI programme in my practice. Due to load shedding on Friday afternoon, 6 December, my network lost it's connectivity to the server. From 16:45 we tried to call the support centre of CGM but there were no answer, inspite of their business hours and voice menu, mentioning that they only close at 17:00. We also tried the emergency number supp**** on the website. The message we got was that the subscriber is not available. I pay monthly support fees to this company and expect them to do better, especially since they don't work on Saturdays and thus can't provide support on weekends, even though most doctors do work on weekends. We even send them emails, but as expected, no reply on why nobody was available to help us on that afternoon.
