"To say that I am dissatisfied is an understatment. DO not use this service. They charged a 175 diagnostic fee which was completely understandable the first time that the technician came out. The technician was evaluating the washer for an hour and reset the motherboard. I was told that it might not fix the problem and that they might have to come back out but that the return visit would be covered by the 175$ initial fee. I called back the next day because the problem was not fixed and rescheduled a return visit. I unfortunately was not in the house that day due to having to work. The technician said that it would need a sensor replaced and proceeded to charge another 275$. They have now charged 450$ for a washer thats only worth about that much and its still broken. I have used other services in the past and I regret not going with them. This company is nothing but a scam looking to nickle and dime you out of whatever money they can. I talked to Tiffany who titled herself as the manager and told me that there was no one else I could talk to."
