If I had chance I would have given rating in negative but unfortunately lowest option is 1 star. I bought semi automatic machine from samsung online store. The product was dead on arrival so I requested them to replace the product. After contact them 100 of times they agreed for refund. They told me I'll receive call from service center to ask if I need coupon or cash back but it did not happen as they said. 2 people came from service canter took the product and handed me coupon without asking my preference and even the coupon is not valid when I tried to redeem. Customer care so pathetic. They just transfer your call from one dept to another and don't have proper solution for your concern. Everyone is giving stupid and unacceptable excuse of why I'm having issue with my coupon. I'm really regretting buying samsung product that too from samsung store. I think I lost my money. Please never buy samsung product.
