Product: Credit card or prepaid card

Good morning, I file a claim against the Best Buy Credit Card service company, since on three occasions I have filed a claim for improper collection for my credit account that they have unfairly decided to close my case, after I tried to make three approaches to fix this charge issue, the claim for the improper charge was for a purchase of air tickets on XX/XX/XXXX, the said payment for the locator number XXXX which is combined with a ticket number XXXX was rejected by of the line of credit on two occasions an attempt to purchase was via the XXXX website and when I did not receive the confirmation I was forced to call the airline asking for a reservation under the name of XXXX XXXX and XXXX XXXX they told me that the payment was declined on the transaction ID is XXXX the second attempt was on the call I submitted the payment in telephone authorization, that can only be done with the same card number card previously registered on the page, the transaction transaction ID is XXXX This information was obtained on XX/XX/XXXX from XXXX XXXX and confirmed on Monday, XX/XX/XXXX, with this information and since XX/XX/XXXX, by XXXX the collection was in Hold, no charge appeared. Therefore, I could not make the claim at that time, since it is necessary to wait for the charge to appear in the account statement to issue the claim, the {$990.00} charge appeared on my statement for XXXX XXXX XXXX  as a XXXX XXXX purchase with references other than those found by me the transaction ID in XXXX and the billing reference in the account statement is a number similar to the air ticket number XXXX that differs by one digit. I called the airline first and the airline confirmed that the payment transaction was not approved by the XXXX on the day As of XX/XX/XXXX, the airline 's customer service, through the different transaction numbers, can not verify where and where this charge was made. They deny having made a subsequent charge and that they never received the payment at the time of the purchase. This voice information and in two emails an open claim ticket XXXX and a cancellation email due to insufficient payment for the locator XXXX indicated that they did not have the payment registered, they could not make my reimbursement. Therefore, I had to process and start a claim with the credit company the claim did not seem to be a problem but the credit company Best Buy Credit Card service managed by Citibank has not been exactly an easy task for the investigations for this charge and they have shown me evidence or they have obtained evidence that does not have my name and does not have the dates of the claims, I can conclude that they manufactured evidence by coincidence since That the evidence that they have shown me has been from my relatives, in this case my mother and my wife and they are trying to say that I do use the air tickets and that the claim does not proceed, I have given them all the information and they to this day XXXX they refuse to review the evidence that is wrong and they do not want to help me. That is why I ask that you communicate with the credit company and we manage to mediate so that they search for and verify all the evidence that really corresponds to my locator number XXXX and under my name XXXX XXXX to my card number. XXXX because they disclosure information no related to me they broke privacy act and fair credit report act.
