Edit: they have since refunded my money which I felt was actually pretty great customer service. My opinion has therefor changed.
Awful service.
They had my tenant's phone number so they could inform her of their arrival for service, but I was obviously the primary contact.
They did the service call, and proceeded to contact my tenant for the next several days attempting to provide updates, despite my calling them to ask for an update the very next day and being told they'd call me back.
Finally 5 days later I call again to find out what's going on and they tell me the dishwasher needs a part replacement but the part is discontinued, so I need a new dishwasher. Bad luck, but it happens.
They ask me if I want quotes for a new dishwasher install and inform me that the service charge I paid (which by the way they made me pay in advance because I wouldn't be present at the service call; another first for me) that would have been applied to the repair cost will not be applied to the labor for the new install. Lousy policy but whatever. I tell them to send me quotes anyway.
Where I draw the line is when 2 days later I still have not received said quotes. In summary, they took my money, told me there was nothing they could do 5 days later, and then when I gave them one last chance to show any semblance of decent customer service, they drop the ball again and ghost me.
All this time my tenants are without a working major appliance. Just the height of unprofessionalism. Pick somebody who values your business.
