I try to keep it simple and clear, but I still have issues passing the front desk. What would you do if they don't sound willing to help at all. I said "I'd like to ask a few questions to the person in charge of x and y" and she kept asking me to tell her the questions which would lead me to pitch and I don't want to do that, then she asks if it is a sales call, but since she is not the decision maker, what would you say? to stop her fron hanging out or saying "not interested" and hung up.
