Terrible Technical Support

They are Ok, I guess, at armed response and guarding, but when it comes to technical issues, they are terrible. Their equipment is not particularly reliable or robust, but the worst comes when there are faults: and despite some incredibly polite back-office staff, when you need something fixed you ALWAYS have to wait for at least 2-4 days before anything can happen: demands for faster service are met with "we can do an after hours call-out" - but that adds a hefty increase to the cost, and on top of that the issues are not always fixed properly and require a follow-up visit (or visits).
