Business ProfileforAble Appliance Repair

On July 3, a technician from Able Appliance Repair made a service call to inspect our dryer which was making a loud, screeching noise. He diagnosed the problem as bad rollers. He returned on July 6 with replacement parts and installed them. Later that day, the dryer made the same loud noise. I called Able's office and they sent the same technician back to our house on July 10 to re-inspect the dryer. He determined that the replacement parts were defective and that LG, the maker of our dryer, had a recall on those parts. He offered to use aftermarket parts but we refused and asked for a refund. The technician said that we had to call their office to request a refund, which I did. The receptionist said that she would have to pull the ticket and call me back, which she never did. Later that day, I called her and she said that she was too busy to get to my refund request. She promised to call me back the next day but I asked for a refund immediately. About a half an hour later, the owner call and told me that they would not issue a refund for a defective part. She also said that she had never heard about an LG recall for defective rollers and that the technician may have purchased the parts from a supplier that sells used or defective parts. It was only after I threatened to file a dispute with my credit card company that she agreed to issue a refund for the difference between the charge of $400.63 and the $110 service call. There are many things that don't make sense to me. Why would Able and the technician purchase parts from a supplier that may be engaged in selling defective or used parts? Why would the technician tell me that there is a recall on LG rollers but the owner tell me that she is not aware of a recall? Why would the technician come back a third time and not have any replacement parts with him? I am very disappointed and dissatisfied with the substandard service from Able and expect a full refund from them for shoddy and suspicious work.
