Your claim is hard to prove but I did some search and found their trustpilot review which is not good at all.

BIG SCAM! Stay away if you want to keep your money. I ordered an S19 Pro, but never really received it. After they confirmed my payment, they stopped all kinds of communication.

And
their Payment method is with BTC ONLY
their Payment method is with BTC ONLY, and has not been accepted by my Blockchain wallet. I have contact them by email, support send me BTC wallet address to pay to it. On their email no name of person mentioned. I requested company bank detail to make payment via bank, or to verify company register because I did not found them on the company directory of USA, they refused all of that. Moreover, they did not provide Telephone number for costumer.
my advice be caution if you deal with Anonymity.

So from last one year they are scamming users. Wish you would read the reviews before placing the order.
It's pretty late for me but it isn't for you..
Good job or I would never have heard of them.
