Welcome to this user forum.
Sounds like the price you were quoted did not include line rental. Are you a new customer, or have you just renewed your contract?
The £24.99 only applies to new customers.
Just renrwed contract for 18 months and the price included line rental i have an email with the agreed price
That seems too cheap, as its the price quoted for new customers.
