Dear Rafael we are sorry that this happened with your order, regarding the image that you attached, you can contact lilyyang@jlcpcb.com to get a suggestion on how to solve the issue, maybe a refund of the dropped amount is good to fix the defected LEDs.

I had opened a complaint and now, I texted her. What's going on with JLCPCB? If people complain, it is because they want you to understand and correct what needs to be corrected. Moving to another company along with the silence is a disaster. Thank you.

@RafaelCamacho We truly appreciate all the advice that you are sending to make the system better and we are considering seriously every single Email, opening a complain is not just to get the refund only but we make the investigation of the main source of the problem and if it is a fault in our production system then we take the necessary measures to fix it and to avoid that the same problem occur again. The best way to achieve this is by sending the Email to the right department which are the quality department ([lilyyang@jlcpcb.com](mailto:lilyyang@jlcpcb.com)) so we are not just trying to close the case but there will be a whole process behind the Email that you will send Mr Rafael :) Please inform the quality department about what happen with your order by providing the necessary information like order number, parts number etc.. Every manufacturing process could have some accidents since the perfect system doesn't exist but the system improvement is important to reach customers satisfaction, hopefully things get better then. Thank you for your feedback.
