My card was hacked, and I reported a fraudulent transaction from XXXX XXXX on card XXXX on XX/XX/2023 for about {$1000.00}. They agreed this was fraudulent and send me a new card. On XX/XX/2023, they put through a second fraudulent charge from XXXX XXXX on card XXXX for about {$4000.00}. ( While the " account number '' at that point had been updated because I was sent a new card after reporting the {$1000.00} fraud, the relevant information is that the {$4000.00} charge was made using the SAME COMPROMISED NUMBER of XXXX, which I had reported as fraudulent, and was from the SAME COMPROMISED VENDOR, XXXX XXXX, which I had reported as fraudulent. 

AAdvantage has now closed my investigation, and this is their finding : " We have completed our investigation and have determined the activity is valid because your bank account was used for payments against the charges. '' I have called them to ask what they mean by this ( if it's been paid, why am I being charged? ). I have spoken with 2 reps and a supervisor, and they can't tell me what it means ; they just repeat " the investigation found this was valid. '' They have refused to give me documentation in support of this incorrect conclusion.

( One of the reps told me they found it was valid because the person purchasing the service used a version of my name, " XXXX XXXX '', which is in the public record. 
( I'm like.. one, that's not even my full name, two, of course 100 % of fraudulent transactions used the hacked card holder 's name, three, if it's in the public record ( which of course my name is in the public record, on linkedin, and various other places ), how does this prove I made this charge? 

On the basis of this nonsense, they are charging me over {$4000.00} and will report me as delinquent on XX/XX/2023 when I don't pay this fraudulent balance. charge. I am a small business owner, woman-owned, and Latina-owned, and I am trying to buy a house this week. Literally. My current XXXX XXXX is XXXX and XXXX, partly because I have a 100 % on-time payment record. They will destroy that in 15 days if you don't take action. Please, I am begging you for assistance. 

I have reported this to my Congressman, whose office is calling them today. I have also been filing fraud reports with XXXX XXXX and with a local consumer reporter. Please, please help me. CFPB is a critical protection for consumers who have such little power against a company that can ruin my credit and charge me over {$4000.00} just because they say so. Thank you, XXXX XXXX
