Hi,dear Ramon Garcia
You purchased this FYY-01 from our store on February 2, and the same day after you paid for it, you emailed us with the idea of replacing it with another machine. We immediately replied to your email and asked you which machine you would like to replace the FYY-01 with. However, you did not reply to our e-mail. We sent you emails on February 5, February 7, March 5, and March 13 asking if you wanted to exchange your FYY-01 for another machine, but we did not get any reply from you. In order to avoid unnecessary disputes, we shipped FYY-01 to you in the afternoon of March 13th, and according to the logistic tracking of FYY-01, it was delivered on March 16th. However, we never expected that you would dispute the order on March 19th, on the grounds that you did not receive the machine. Once again, we sent you an email on March 19th with our doubts and we don't understand why you did this. We thought that you would not reply to our emails as you did before, but this time you replied to our emails immediately and treated us very badly. We don't understand what we did wrong. You say that our customer service is a concern, so we would like to ask you what is wrong with our service?Thank you for your suggestions in advance, we believe we can do better in the future.
