Business ProfileforGentle Monster

I am having a terrible experience with this retailer. I placed an order on May 5 for a pair of sunglasses, using Klarna to pay for it. I received a confirmation from Klarna immediately, and my payment was processed, but I never received an order confirmation from the Gentle Monster. I followed up via email the next day to ensure my order actually went through, and they responded letting me know my order was processed and they provided the order number. After I never received a shipping notification, I followed up again on 5/9, and they responded saying my glasses had shipped and provided a ***** tracking number. When I used the number to track on the ***** website, it was for someone else's package that was delivered in ******* on May 8. I also went on the Gentle Monster website and used the "Track Your Order" link on their website and input the order number they provided and all I get is a popup that says "you order does not exist". I have followed up via email 4 times since and no one has responded. I also tried calling the customer service number listed on site multiple times and days, and it goes straight to voicemail and just says "this number does not have voicemail setup". At this point, I am wondering if this is a scam and they just took my money. Totally unacceptable. I need an update on if my order actually exists and what the true status of it is.
