Hello and welcome to Tom's Hardware Forums.
Yours is a very confused and confusing situation. From "it never shipped" to "it finally arrived" is not unusual and a delay of ten days is not always the fault of the shipper. You don't name the company or link to their advert but if you look carefully and their conditions, you will probably find they ship refurbished products. It's a case of buyer, beware when purchasing parts on the Internet.
