I believe they are a legitimate company that is now scamming people by accepting their money and having no products to send and therefore claiming that no money ever arrived.
This is bad when a company that was once legit becomes a scammer because there were positive feedback and good customer testimonials before they started scamming people, I'd like to ask how far will you go if the bank cannot reverse the transaction, will you send a representative to their location to charge them since you have a piece of complete evidence, in return you can ask on the court for damages from this company, this is fraud and they are liable on the laws where they are located.
It is not only happening for the companies. The same thing happening on the forum. Many a user make small transactions or repeated transactions and then become a scammer. It happens both for trading as well as lending. Actually, their main tendency is to scam like a Ponzi scheme.
