I purchased a 2 TB "incredible" pen drive for USD 40 (USD 44,98 shipping included) from the site www.popuor.com (which is now unavailable) and received a 32Gb pen drive + 1 bluetooth earphone (one side only). The item was purchased via PayPal. I tried to contact them back but the emails and site are all down. I contacted PayPal and filed a complaint. After a few days, I received a proposal from the seller to refund me USD 15 which I refused. Some more days later Paypal wrote to say that the seller would refund me if I ship back in express with a tracking number, the items in their original packaging. I decided to go ahead and it's costing me USD 35. I'm not sure they will acknowledge receipt and that the items are those they sent.
I discovered that hundreds of other clients suffered the exact issues and even filed several complaints to PayPal on the paypal's community page regarding this company. What is weird is that PayPal is still working with these scammers and still supporting their business.
