Dealing with the UK Border Agency part 2

This process does not get any easier. I've made several calls to the UK Border Agency today over the past three hours or so and each time I have reached the very end of the options you have to choose from only to hear the following message, "All of our telephone operators are currently busy and you will have to telephone back if you wish to speak to us." And then the line cuts out. They are not even putting me on hold any more. I will keep trying I guess.
