We have put together a short survey to capture your feedback in terms of what BT can do when you experience home Wi-Fi issues. We would appreciate it if you could take a couple of minutes to complete a short survey. Read more from here, Fix my home Wi-Fi
I cannot find a way to see my existing calling features except by using the Change Features option then cancelling the order.
Also I am on Unlimited Weekend Call + Anytime Calls but the Anytime does not show up on MyBT althought this has been promised to be coming for months.
I think that is the only way you can view them, unless somone else has found another way.
If you just want to check what you have rather than a recent change, you can look at your current bill. Having add-on details shown in MyBT is a forlorn hope.
