Called local number 972-200-3866.  Called to get an estimate for Garage door off track. Brian Crosek, Tech came out and mentioned it will take about 15-20 mins for $169. I asked for written estimate as it seemed high for 15-20 work. So i declined to fix. Brian mentioned that he will email me with notes. When I received the email, it was only the invoice for $19 for which wrote the check. But, no estimate. He asked me to call the office. When I called the office, the floor manager said they dont give written estimate.
