Dr Sylvester is a THIEF. They won't tell you that it's NONE refundable if something wrong with your order or glass. They won't return the $ to you and yes, if they exchanged, but they will ask you to pay more on the exchange item. Please read the my story. At first we thought they are nice to their patient. We brought our son there for an eye exam. His first glass was $270. He lost it and we brought him back in. This time I don't want to buy it at Dr Sylvester office since it's too expensive. So, we only want to pick up the prescription. They refused to give it to us. Instead they asked why and tried to convince us to buy it there. We told the truth that we found Costco has a better deal. They said it's not a problem, they can match Costco deal. It turned out that we paid $10 MORE but I didn't mind. Without knowing their order did NOT include the same package that COSTCO has, two weeks later, the frame felt apart. I called them and they said they will replace the lens for me and asked me to come in the office for further discussion. I couldn't go at the time, so I asked my husband to go there. It turned out they tried to sell him something else and charged him $190. My husband didn't notice the bill and signed it. Gosh, I don't know where his mind is. After 10 minutes, he got home and I saw the bill. I asked him why they charged you $190, he said he doesn't know. I called them right away and asked for CANCEL the charge. She said she won't ( I believed it's Dr Sylvester's wife ). She refused to talk to me that say and will talk to me tomorrow. I called the next day and she said it's non refundable. I either take it or she only can give me credit. What's a THIEF ! !! PROFESSIONAL THIEF WITH DR DEGREE. It's an awful experience that we have to go through. Now, We have NOT yet receive the glass that they ordered for my son. :-( We had to buy a different at Costco.
