My broadband is down at the moment due to (according to MyBT) a major service outage due to planned engineering work in the area. It also says that 'Broadband Backup is unavailable'.
Now this begs a number of questions:
Ring 0800 800 150, ask for the Halo backup to be enabled or sent if you don't already have one, an MSO is still a total loss of service.
I spent an hour waiting to report the issue; the battery ran out on my mobile. This is a service I pay extra for and I can't get a resolution. My point is, BT know I have Halo2, they know the service is out and do nothing for the extra I pay.
