Yes you do. The company gave you an estimate and you relied to your detriment on that estimate to purchase the furniture when you could have gone elsewhere and either possibly paid less or obtained the items earlier. You need to put your issue in writing and either contest it with the credit card company with which you used to pay the furniture or if you paid cash, you need to inform the company in writing you expect a discount or you will file a complaint for theft with the attorney general because in essence the company took your money and hasn't given you the bargained for furniture. This is why you always pay a minimum up front or if you special order, you indicate the company has recourse by simply selling the specially ordered furniture. Furniture (unless it is really off the wall) can always be sold; it is not like a custom made initialed item.
