There's a similar problem turned up with two of my banks. I had 2 lloyds accounts and when they split the company they sent one to TSB. The home phone number I use is UK style staring with an 0. Now they want the number with +44 international style for Visa to do the payments and of course it doesnt work. TSB seem to have automatically updated their number properly but lloyds haven't and they've just closed the local branch and when I try and change it online it cant seem to phone me with the one time password!
