Hi mine shows £17 signed up to (£12) so i assume its just showing the normal price
At first mine was showing £17.00 but now showing £12.00 may be it just takes a few days to sort it self out . If you are still worried just give BT a ring and i'm sure they will correct it .
I've just signed up for this too and mine also shows £10 (including all discounts) I do not want to be charged £10.
Has anyone esle experienced an incorrect charge?
Update to this - I've just come off the phone to Customer Options who assure me that I will only be charged £5 - this is because I am an existing customer with a BT Landline. Looks like the app does not show this, only the standard £10.
