If I could give 0/5 stars for Samsung affiliated appliance repair company NISI-USA, I would. I can't speak for all company locations, but avoid Houston location at all costs! I'm honestly surprised Samsung would work with a company that's so unprofessional and has that terrible of customer service.I Wouldn't recommend this company to my worst enemy. Scheduled an appointment for before 12pm and got notified that the technician would try to be there between 2-4pm but due to rain and traffic would probably be late. When I told him that the appointment was never supposed to be between 2-4pm, he said that only the technician can confirm the time and that it was documented as tentatively between 2-4pm and that if we couldn't do that then to reschedule. When rescheduling, I was told by NISI USA Houston that they wouldn't be able to fix our dryer until 10/10 (leaving us approximately 2 weeks without a dryer). When the customer service member told me there was nothing that could be done I asked to speak with the manager because it was inappropriately scheduled to begin with. When I spoke with the manager, he wouldn’t take even 2 seconds to listen to what me and my fiance's concern was and instead spoke over us the entire time. When my fiance asked for him to please just listen to what our issue is before speaking so that he could properly understand our problem and help us appropriately he wouldn't do that and instead kept speaking over the top of my fiance before purposely hanging up with him. Within minutes we were notified our service ticket had been cancelled (WITHOUT OUR CONSENT!). When calling back to try to speak with him and get his name, he continued to speak over the top of me and would not give me his name or let me speak with anyone else and hung up on me. When I called for the 3rd time he said "Hi this is Robert" and that's the only reason I found out his name. Terrible company which I'm sure is a top up issue. Robert should be fired! What happened to customers come first? The least he could do was listen. Doesn't care about customers and EXTREMELY unprofessional. I called Samsung and was offered to work with another company (Alice Technology Inc.) and they were day and night better! I’m surprised they aren’t the preferred company for Samsung because they were so professional and we able to schedule us for the following day in the morning. Avoid NISI USA where Robert is the manager at all costs and ask someone for someone else to work with even if it isn’t Alice. You’ll avoid the headache and frustration and I promise be much happier you did!
