So basically VM are inferring that their cable services are the dog's danglies and xDSL services,
which include their own National service, are rubbish.
Criticising a technology used to provide one your own services is a strange tactic indeed.
I note no distinction is made between ADSL and VDSL services.
So I take it VM are inferring that their cable service is superior to BTO's VDSL service when it just plainly isn't.
It seems to me the claims VM make here are just as economical of the truth as their "unlmited" claims.
