Not the same situation but reminds me of the time I cancelled my cable service.
I called them up and said I'd like to cancel. They said, no problem, for what reason? I said because I do not want it any more. They said, no, you do not understand, we have to have a reason. I said the reason is, because I do not want it. But whats the reason? Because I do not want it. .... and on and on.
It took a while but they gave up.
