Now back on line.
Voice back first then BB mid afternoon, but with an interesting twist. TT would not recognise my user name and password, gave a message to change my password back to the one I was given when I first joined, and call the freephone number (from my TT phone) if I have forgotten it.
As it happened I had the original letter and changed the password, no joy. Tried the TT number a couple of times (just in case), kept getting told there was an error. At around 7.30pm I got through. The password TT hold for me is not the password I have been setting up routers etc for the past 18 months. it was a very simple password TT tried when we were troubleshooting 2 years ago.
What on earth has happened?
