I use 'My BT' regularly to check my home network, bills etc but today I am unable to sign in. We suffered a power cut in our local area yesterday and today I noticed that our wifi has been much slower than usual. As a result, I decided to log in to 'My BT' to check the speed. The first obstacle I encountered was that I had to update the app. Then I had to sign in - which is when started the problem. I was unsure of my password so chose the try to reset it by going down the "Forgotten your log-in details ?"route. Although I have been typing the correct ID, I keep getting the message "We can't find a BT account with that ID". I've tried using my laptop, rather than the app, and the same happens. I have also tried entering my BT landline number to retrieve my BT ID and get the message "We can't find a BT ID associated with the phone number you've entered."
