Frustrating international service

I am unsure if Lloyds TSB is that same as Lloyds International Banking - my complaint is with Lloyds International Banking. I can log in up to the stage where I the 4 digit code is issued. At that stage I either do not receive a call to try and enter the code or I do get a call but my code is not accepted by dialing it in or saying it. Very frustrating as I need to be able to transfer funds while travelling. The only reason I gave 2 stars is that they are very helpful (but usually unsuccessful) when I do phone them.
