Re: Ripoff merchants!
Anyone can screw up an order, the real measure of a company is when they fix it. Or not.
If you still have the original box, packing materials, etc., you might want to look at the weight on the shipping label, and compare that to the actual weight.
Since your missing pieces are stainless steel and presumably have some weight to them, if the box you got weighs what the label says it weighs, then you have proof that something was not shipped to you.
In addition, even if there's a weight discrepancy on the box (i.e. if the shipper says 6 pounds and the box weighs only 3) pretty much every box from every carrier (except our postal service) is actually weighed in transit at least once when it goes into the first depot. And at that point the tracking number and weight are recorded and the shipper is usually billed by the actual weight--not the weight they entered. So if there are discrepancies, it is also possible that the real weight can still be determined from shipping records. You might have to file charges of postal fraud in order to get those--but they do exist. Just the threat of "Do I have to file charges to obtain the records to confirm this?" may bring someone around, because those charges would cost way more than simply fixing the order.
If you have the whole box and packing, weigh it, advise the card company, that helps substantiate your claim that you were shorted.
