Ray-Ban Order Not Delivered and Tracking Stopped

I ordered two Ray-Ban sunglasses, Dark Green Classic and Justin Classic, on 8 August through the official Ray-Ban website. I reached this site from a Snapchat ad and completed my purchase there. After placing the order, I received a shipment update email from Ray-Ban for order number 1726, but since then the tracking has stopped working and no current information is shown. Until now I have not received my sunglasses. The tracking number and shipment information no longer show any status or movement. I am very confused because I do not know anything about any person named “Abhishek”; I did not buy from any individual or WhatsApp contact, only from the official Ray-Ban site that appeared on Snapchat. I request a full refund of the amount I paid as soon as possible, because I did not receive my products and there is no working tracking information. I also ask to be clearly informed in writing about what went wrong with this order and how my refund will be processed.
