Hanging phone up on you!

I called Mark a week ago, explaining that I need his expert advise on existing gutters and for modifications to be done. When calling today, I asked him why he has not been on which I received the answer that he will only come if there are other business in my area. I asked a simple question of should I then also give other people the option to quote on which I got the reply - \Do that"and then hanged up the phone on me! THIS IS NOT HOW YOU DO BUSINESS NOR TREAT CUSTOMERS! """
