You have to do it as a separate thing, by updating your phone options, and ticking the box relating to the free caller display.
I recently received an email from BT saying that my Line Rental Saver was due to expire soon and with it the free Caller Display. Now I don't have the email anymore but I could swear that the email said that if I renewed my Line Rental Saver for another year then I would continue to receive Caller Display for free, so I duly renewed. Now I have just received my online bill (which shows I have renewed the LRS) and there are advance Caller Display charges from when the current LRS expires on 15th May. As I don't have the email anymore I can't be 100% sure but could someone set the record straight for me, as I feel I have been duped!!
Have a read of this thread.
The email probably said that if you renewed your Line Rental Saver you could creceive Caller Display for free. What it fails to say is that you need to order it.
Thanks vofsanity2. At least I'm not the only one confused or having problems! I'm sure BT could make the whole thing simpler if they wanted to.
