I prefer paper billing but was forced to sign up online to get BT Sport. As mentioned you can set up paper AND paperless online.
However...I also spoke to the helpdesk and was told that to remove paperless and revert to paper only can be done on request by a supervisor.
As usual when ringing BT I recorded the conversation.
Do you remember the good old days when we received a good discount for paperless billing? In a few years time we will be remembering when we used to get caller display and Answer 1571 for free.
These days it works the other way round. You don't get discounts. You get to pay more unless you do it BT's way.
The idea that it costs £2 a month to process payments is nuts. I pay all my other bills through on-line banking, only phone companies charge me for the privilege of not having a standing order.
You underestimate your perceptiveness. In a few months we will be remembering when we used to get caller display and Answer 1571 for free. BT starts charging for them in January.
