I call churches for a living and have a question? (kinda long sorry)?

I work for the history channel and call churches for a living.. I speak to the pastor typically and briefly tell him about "The Story of Jesus" a dvd set that outlines the life of Christ. They dont have to purchase anything and they can watch if free for 30 days on a preview period. I am treated very rudely by those who work in the church and have had pastors hang up on me more than once. I spoke to a Priest today who told me "you should take into consideration we already have our own curicculum and way of doing things' in a very condescending tone. I always have a friendly and personable approach and genuinely believe i am doing good work for the Lord. I was very offended and fired back "You should take into consideration this is my job and I do this for a living". Its almost as if he wanted me to feel guilty for calling him. The call didnt last very long after that point but it sincerely has been bothering me. I want to explore faith and see how it can positively impact my life and maybe others, but at the momen i just dont see how a just God allows such shallow, petty, and cold hearted folks get into a position of faith leadership. Its not acceptable for me as a believer in God to think that its ok to treat others poorly so long as you lead a congregation and treat people well at church. I can understand they might get frustrated over recieving many sales calls a day but we are all Gods people and being a telemarketer doesnt change that.
