<human>: Can you give me the gist of the text in a nutshell?

I am a new home owner in Washington County OR.  When I closed on the house I got a one year home warranty for about $500.  I have successfully used my warranty twice before.  Once they came out to fix our disposal, which they replaced with a new one.  Great.  $75 paid.  Another time they came out to tell us our heater was not broken and they couldn't do anything but gave some helpful suggestions to reduce the noise.  Great. $75 paid.

Both times prior to that I was able to speak with a representative to schedule the service call.  This time I called because my rain drain was clogged and I needed to have it cleared before fixing my gutters.  I could not get a representative on the phone.  They moved to an automated system to place service calls.  I tried multiple times to try and talk with someone.  In the end I used the automated service.  The plumber came out, looked at it and said he would call it in to the warranty company.  He came back and said it's not covered.  I tried to hire him outright to do the work but he did not have the right equipment.  Then he asked for the $75 service fee.  I said that I didn't think I should have to pay because we could have addressed that it wasn't covered through the initial phone call.  He said that I didn't have to pay it.  In the course of our conversation he also said that he knew on the service call exactly what he was coming out for and agreed that they knew ahead of time that it wouldn't be covered.

I have now received a bill from the home warranty company.  Low and behold there is a phone number to make payments where you can actually get someone on the phone.  I spoke with two separate employees and explained the situation in detail to both.  The first employee said that he completely understands and that he would need to transfer me.  The second employee said that I am fully responsible for the $75 because a service call was placed using their automated system.  There are no supervisors to talk to.
<bot>: Home warranty company charged me $75 to send someone out to tell me the repair isn't covered and won't waive the fee.
