A. Research the seller's reputation before making a purchase. Look for reviews on independent websites and forums to see if other customers have reported receiving counterfeit items. If you suspect an item is fake, document your findings and consider reporting the seller to consumer protection agencies or online marketplaces.

B. If you have already purchased a fake item, gather all relevant documentation (receipts, photos of the item, etc.) and contact your payment provider to dispute the charge. Many credit card companies offer buyer protection that may help you recover your funds.
