Commonwealth Appliance Service

I had a service call on 07/22/16, 2nd visit by the technician name Ian who was very unprofessional, Rude, no knowledge of the fridge. He wrongfully diagnosed and changed an expensive part. The leak was due to a crack on the water tube, but he changed the Housing for which he billed $78.51 , He also broke the cover on the top and when I asked to fix, he said he will come back. I asked him to write it on the invoice, he refused. Not sure he will come back?
