Hmmm, that's a toughie. Lots of times stopovers have to be booked with humans just cause .bomb is not smart enought to do it. So is the CSR saying it is allowed? If so, I would ask for them to waive the fee for this and book it for you. I would otherwise be inclined to say that you should call web support, but they really are not helpful and would not understand what you are trying to say.
