Drifta not working

We have a Drifta for more than two years and was working fine till last Friday evening when service simply stopped. Services are scrambled. On Saturday I have phoned countless times only to eventually been told the problem is on their side and they will escalate to IT who will fix within an hour. Seven days later still not fixed and no call. Called them again today only to be told that they have a technical problem and that not a single Drifta in South Africa works at the moment. They also dont know how long this problem will last. Is this really true? Every Drifta in SA not connected??
