After contacting Samsung with a problem with my washer/dryer, they informed me that I would be contacted I. 24 hours by the repair company. A lovely lady from Alpine Refrigeration and Airconditioning contacted me the next day, checked my details, gave me a time frame and advised that on the day of the appointment, the technician would contact me prior to arrival. True to the promise, Will rang to tell me he was 15 minutes away, he was courteous, knowledgeable and very thorough. Best of all, less than 30 minutes later, my machine was working. Well done Alpine Refrigeration.
