THEY HAVE STOCK UNTIL YOU PAY THEN THEY DONT

Hi,<br> <br> They are selling computer parts on Bid or Buy. I bought a CPU threw them on Monday, they said they have stock until I paid them now they are telling me they dont have stock. They said they will get stock the end of the week, so I waited and then contacted them today and yes still no stock. Now they want me to pay even more money over to them for another CPU which is identical to the one I purchased. So they can just tell me after I payed that they dont have stock anymore again like the previous one.
