Alright people, you can forget about all other appliance repair companies. These guys are simply outstanding. From texting to advise when a serviceman will come (with updates), to courteous service advising on how to save money, to prompt follow-up. All very professional. But the clincher is: error code on 5 yr old Samsung washer said electronic door replacement needed. Part was ordered and installed. Didn't fix it. New error code, said replace mother board. Part ordered and installed. Worked when repairman tried briefly. Next day, didn't work. They amazingly took back and didn't charge for both parts, refunding me all the costs except the initial ~$70 service call. Hats off to Dmitri for his management, to Ali and to Viktor the repairmen. Full experience totally blew me away. Now gotta buy a new machine.
