Found some info about the price rises
"Amongst other things the provider is upping standard landline line rental from £13.90 to £14.99 from 1 February.
Its standalone broadband and TV packages will also rise, as well some of its 'collection' packages.
The latter are bundles of different phone, TV and broadband services.
Other than the price of standard line rental, no other call costs are rising."
