Mtc Plumbing And Drains

I have 2 service calls from Troy at MTC Plumbing. The first was to install a sink in my bathroom, with a plan to come back and install a kitchen sink and dishwasher. After the first service call the new plumbing leaked. When he came back for the second service call they fixed the leak and then installed the sink and dishwasher. Then I discovered they did not secure the dishwasher, so it moves after being installed - not ideal. I called to asked for this to be fixed and Troy refused. He then became defensive and took no responsibility for his work.
