If you have problems during an online transaction, try to work them out directly with the seller or website. If that does not work, file a complaint with:
Your consumer protection agency.
The Better Business Bureau (BBB).
The Federal Trade Commission (FTC).
Your state Attorney General.
Econsumer.gov, if your purchase was with a foreign retailer.
If you made your online purchase using your credit card, you can dispute the charge with your credit card company.
