I'm so sorry to hear your service is affected by a planned outage and that you weren't notified of this. This is not the level of service we aim to provide and we apologise for any inconvenience caused. We always try to send notice via letter for any planned works, apologies this wasn't the case on this occasion.
How are things performing with the service currently? Has the outage been resolved? If so, are the drops in service still occurring? Do they affect both wired and wireless connections?
