First: Sears customer service is obviously outsourced to some foreign country and they can do little to help. They just take down your complaint, and can only look up the same tracking information you can.
Second: Sears seems to be in the habit of posting items on very good sales, confirming the purchase, and verifying the item was shipped, when the item was not really confirmed or shipped.
They did this to me with a combo set of power tools, and after 4 weeks of trying to follow up, I was sent a UPS tracking number for a package that would have weighed around 20 pounds, showing a package delivered to the wrong state weighing one pound. When I inquired about this, they did not ship me the items, instead refunded my purchase price. I told them I did not want a refund. Since they had confirmed the purchase, and verified the shipment as if they really ever had the set, and I had waited 6 weeks, I want them to ship me the items.
Every item in the set, they show on hand and in stock. Even though the sale value of the items sold separately is higher, they should absorb that cost to provide the items I ordered and fullfill their commitment. I think Sears is quite capable of absorbing the additional expense for something that was their error.
If they never had the sets, or the advertised price was a mistake, they should have admitted that immediately instead of pretending to fullfill the order, and then pretending they don't know what happened. If this was the case, by the next day after ordering I should have recieved a cancellation due to ad or stock error, rather than a confirmation.
