Unresponsive and uncontactable.

Line down for over a week. Online reporting App doesn't work "We are aware of the problem - check back in a few minutes" - tried that for a few days - unable to log fault. Then logged callback requests about 8 times. Mostly no callback or calls dropped with no response. Eventually managed to log a fault after about 5 days of being bounced. "Technician will be in touch". Nothing 4 days later, no contact, still waiting. 2 further callback requests logged, with no response. It is virtually impossible to contact anyone, there is no useful response to online fault logging, and their staff don't call back.
