I am yet to receive my formal letter of notification but I have been able to check via the online link posted on other threads showing bespoke rises.
The online tool confirms my Infinity 1 + calls is increasing by £2.50 / month.
However, I have BT Sport in HD on Sky but this does not show in the headline rise and if I scroll down to the BT Sport price changes the table there shows a £2 increase.
Should I assume my rise is actually £4.50 in total or am I misinterpreting?
