Is Sedimy a Scam? sedimy.com Online Store Review

I think Sedimy located at sedimy.com and sedimy.shop is a scam. I ordered from the website because it is very professional and slick, but they never replied to three of my communications, two of which were to ask for a tracking number which they never provided. When I ask PayPal for a refund they did an investigation and found that the item was in fact delivered to Denver Colorado, which is where I live, but not MY address. The USPS would not provide me with that address per their policy, which is fine but now I'm trying to get a refund from PayPal and it's just a big hassle.
