ABC APPLIANCE SVC CO

I told the tech black material was building up in the tub and along doors.  He turned hot water on in sink and said water temperature too low to dissolve protein material.  Instructed to buy Lime Away and that would take care of problem.  I explained that previous service consultant took apart basket from drain and removed debris.  He would not do this.  I told him the soap dispenser was broken so then  he checked that.  I asked if the top rack needed repair and he said yes.  I had to walk him through the steps of the analysis.  Another adult was present and could not believe how he declined to address the debris in the basket and seemed rushed to get out of my house.  A rubber bumper piece was missing from top rack so I asked if he could replace it?   His answer was " if I have one in truck' otherwise I'll fix it when I return to fix other items."  However, he did not have the quote for the parts and did not know if we would choose to repair it at that point in time.  In other words, he did not fix issue I called for.  When the office called back to quote the repairs, its was another 375$ so we declined and bought a new dishwasher.  This all happened week before Christmas so there was some urgency here.  They advertise 24 hour service. I called Monday.  Since it was not an emergency I agreed to an appt. on Wednesday.  Then the tech couldn't wait to get out of my house.  Visit took less than 10 minutes.  When company called back regarding ordering the parts I told the secretary what happened and she commented that they had had previous complaints about the tech.  I did purchase Lime Away and ran 6 cycles without resolution of problem as well as turned up my hot water heater. 
Background-  My Dad was a Maytag tech and I went on calls with him. We always checked the machines for typical problems not just what the client noted.  It's called comprehensive service.  And you listen to the client as to what the problem is.  The tech discredited my knowledge. I would not use this company again as they keep this tech who is not interested in serving the client needs.
