Appliance Repairman

Dishwasher was leaking. Technician arrived and gave me a quote for $325 to service it. An hour and half later, he told me he needed to replace a part. I asked him how much it was and he didn't know but would get back to me. I paid the bill. He told me he turned the water off. I had to follow up over the next 4 bus. days to find out about the part - nobody had called me. I was told it was a $750 part. Crazy! Then water leaked all over the floor - he didn't turn the water off. I should have been told the full cost so I could have considered the option of purchasing a new unit.
