Twice in the last 6 months I've lost internet for a week or more. Multiple calls to customer service still have not resolved the issue this time. The faults team is utterly incompetent, they remotely assess the fault, blame NBNco or the modem (neither of which is actually the problem) and close the job ticket without actually resolving the problem. Great way to lose a customer of 11+ years.
