Technician wrote on invoice "nothing wrong was found" yet invoice has charges for parts and 1.5 hour of labour although technician was not on site for 1.5 hr (as per witness). Upon receipt of invoice, called Blue Mountain who were supposed to call me back. Yet they called a third party despite the fact that I had stated that I was the only person they should contact (as the owner). When I called again, they refuse to talk to me. I would never deal with them. I find their practices dishonnest and their attitude unacceptable.
