It appears they are a little confused themselves though!
Quote:Call charges
Calls to 03 numbers from any network will cost no more than those to 01 and 02 numbers and count as part of any call package. The cost of a call to an 0345 number will depend on the network. Please check with your provider. BT customers may be able to call 0345 numbers for free.
Or did they just forget to delete that wording when they changed the 8's for 3's in that paragraph?
