Sos Appliance Repair

They were called to repair a sub-zero fridge which was showing a "service" warning. They arrived promptly, examined the unit, and declared that the fan motor required service. They were there for 35 minutes, claimed that the issue had been solved and charged $350. The next day the "service" warning was still showing and there was a burning smell emanating from the fridge. Another repair man from a competitor was called, examined the fridge and said the fan had not been serviced. I was overcharged for service that was not provided.
