One of the benefits of making purchases with a Visa card, is that you can reverse a charge if the product you ordered never arrived if it arrives damaged or if a false charge is made.

If a merchant will not reverse your charge, Visa will handle it for you, and thoroughly investigate your official dispute.

Return to the merchant and ask to reverse the charge to your Visa.
If the merchant won't work with you to reverse the charge, move on to Step 2.
