I recently filed a fraud claim on my card because a merchant from europe charged it up to the tune of $2500. I didn't recognize the merchant at all, as the description the credit card company had for the merchant is in no way related to the actual charge. I am now remembering that I had authorized a $50.00 charge and thinking that it was charged through this merchant and they decided to take some extra. Can I call and amend my claim? or change it do a billing dispute? I have already returned an affidavit of unauthorized use and I don't want to go to jail for perjury because I forgot about this one charge, that by the way, the amount does not match the charge either. I authorized $50.00 and my card was charged $49.99. I never received the product I bought either so either way the original charge is fraudulent, but I can't remember if it was a securecode transaction or not.
