I am extremely frustrated and disappointed with my recent order. I specifically ordered prescription sunglasses with the demo color BLACK, yet you have provided me with clear lenses instead. This is absolutely unacceptable. I spent almost $600 on this order, expecting to receive the correct product in a timely manner. Not only did you fail to fulfill my order correctly, but you also did not ship the item the next day as promised. I have been waiting unnecessarily and still do not have the sunglasses I paid for. I demand that this issue be addressed immediately, and that my prescription be correctly applied to the sunglasses matching the BLACK demo color, as originally ordered. I expect a prompt resolution and an expedited shipping process to rectify your mistake without any further delays. Please confirm receipt of this email and provide a concrete resolution today. If this issue is not resolved immediately, I will be left with no choice but to escalate further. I look forward to your swift action.
