Revenue Generating Units?
As the only way to get a marginally acceptable cable price was to accept a "Loyalty" bundle including a landline phone that has not been used in 6 months it's not surprising to see voice revenue decline. Their phone was always over priced, only the early fibre made it a viable option.
Fibre has been generally ok, but always necessary to chase them about price rises.
I'd happily shift to alternative fibre options but do not have, or want, a fixed telco line installed. I suspect that makes me an easy mark for Virgin as well...
