The A Team Appliance Repair review: Never call this company - just a cash grab

I am an operations manager for a 20-million-dollar a year service company, and if I treated my customers the way I have been treated, I would be out of a job.
1st ask about their hourly rate, they don't have one. The first tech that came out was nice enough but took all of 10 minutes to determined by going through the board that I needed a new board. Was provided an all in price which ok it is what it is and the office should be in contact with me within a week to schedule once the parts arrive. He recommended the fix because the newer product is garbage and is constantly breaking down. The office calls to set up the new appointment, a different tech comes in, installs the board and states you now need a new switch and the cost of this new switch and labor I could have replaced the washer with a new one. Tech also stated that this is what was actually needed to repair the machine and when asked why I was told the board would fix it I can't tell you because I did not attend you first call. I called in and asked to speak to a manager, was told no managers work on site and send an email which took a week to respond too with a supervisor form the call center not a manager. We require full payment for the last visit before we order new part. Either you pay or we will send you to collections. Then I was hung up on when I stated I would not pay and wanted a manger. This one might be worth legal action. Apparently when you find all of their reviews this is not uncommon.
