We have had someone come out 3 times to do a dishwasher installation. Last time was at 9 am. I waited from 8:45. until 9:20 when I had to leave. When I got in touch with Mtn. Mechanical they said that I was a no show and they would have to charge me a $50 fee to send some one out again. They claimed their technician had waited from 9:00 - 9:50 and had even knocked on the door several times and no one was there. They also claimed that they had called my cell phone and no one had answered. This was impossible since I had sat on the front porch from 8:45 - 9:20 while I waited for them and I had my cell phone out in case they called. I had no missed calls and no voice mail messages. They do shotty work and lie to customers.
