Best Dishwasher Installed in North Las Vegas NV

I had requested 4 things be completed they only did 2 as I wasn't there my roommate was to let them in. I emailed them very specific things I wanted done. So I emailed them back and I was told they were waiting on a tech and that was over a week ago. In addition the vent they installed they ripped. Told me I was charged for what they did. Meaning I was charged 185 to hook up a dryer and tighten a pipe. Just overall negative experience.
