If you do not receive the item you bought and previously filed a customer complaint with the particular vendor but to no avail, you may request assistance from the customer protection service in your area.  Furthermore, get in touch with your credit card company and let them know about the complaint. These days, the use of rebates has been slowly increasing due to the fact that it is a super easy means of decreasing the actual price of an item, without the merchant needing to obtain price protection.
