I got Clarence Porter's name from my home warranty company. He came to fix my bathtub diverter. It's a super easy fix. Now a year later I find out he didn't fix it correctly and it has been LEAKING. The room next to the bathroom has mold along the baseboard. I didn't notice it before because there was a bookcase on that wall.
So I called them to ask what could be done. The receptionist told asked if I had another claim with the insurance company and after I said I did she said they could come back out. (Of course I would have to pay them the $100 for the claim.) I told her I did not want them to come back because they obviously didn't do the work correctly the first time. I wanted to know if they guaranteed their work. She said they "only have to guarantee the work for 6 months because that is all the warranty company requires." I told her it was very obvious that this had been leaking for quite awhile and only did it when someone showered in that bathroom.
She said that was too bad and that there was nothing they would do. Then she said "hope you have a good day, good bye."
Then 5 minutes later she calls me back and tells me that had I not been so rude to her they would have come out for free. And then hung up on me.
