Query: Computer Brain sells this item and you would be a fool to buy from them

I ordered this scanner through Amazon because it was highly rated. I waited nearly four weeks for delivery and then my order was cancelled with no explanation after I inquired about the delay. Amazon claims it has no control over third party sales, yet I ordered this item through AMAZON. The point is, you would be foolish to order this scanner through Amazon since the order goes to Computer Brain and they simply don't care that they are out of stock when they accept your order. No communication, no warning, merely accept the order, then cancel it. Who cares. And Amazon apparently does not care either.
