Product: Credit card or prepaid card

Chase fraud investigation failed to conduct any research or request any information from me to prove that I did not purchase and use a ticket on XXXX XXXX on XX/XX/XXXX. Chase fraud department has displayed a level of incompetence and has assumed that I am guilty due to the name on the purchased ticket. 
On XXXX XXXX my Chase Amazon credit card was charged five ( 5 ) times to purchase airline tickets from XXXX  XXXX ; as well as, from XXXX XXXX. After being notified of purchases via text message I contacted Chase company immediately and stated on recorded line that I had not purchased any airline tickets. Chase company assured me that this matter would be resolved and not to worry about it! 
After two months of investigation I received a call on XX/XX/XXXX from XXXX at extension XXXX with the request to call back. I called back Chase Fraud Deportment immediately and left a voice mail ; however, nobody took time to call me! On XX/XX/XXXX I received a letter from Chase company dated XX/XX/XXXX stating that due to Chase investigation they came to the conclusion that I received benefits from this transaction ; therefore, Im responsible for {$530.00} and this amount will be charged back to my credit card. 
I have filed a complaint with XXXX XXXX ( case # XXXX ) and was able to obtain all purchase information that Chase fraud department failed to obtain. 
I further filed complaint with XXXX due to breach of security ( case # XXXX ) and notified them that the person was able to enter a secure area without proper legal identification that matched the name on the airline ticket. 
Lastly, I filed report with XXXX XXXX County Sheriffs Department, case # XXXX. 
Chase fraud department never contacted me to discuss my location when the transaction took place and never asked me about any activities during this time period that I was supposed to be flying from XXXX to XXXX ( information provided by XXXX XXXX ). 
Due to sensitive nature of my business my credit report is carefully is monitored and is disclosed to any current and any potential clients. Any remarks are noted on my U-4 and is open for public disclosure before a prospect decides to work with a financial adviser. I manage over XXXX in client assets with an income of $ XXXX ( + ). 

Furthermore, my activities during the week of XX/XX/XXXX to XX/XX/XXXX ) was : a. On XX/XX/XXXX I was at home all day ; b. On XX/XX/XXXX I was at work all day ; c. On XX/XX/XXXX I was at work performing notarial act for my client that can be verified with notary log and letter from the client. 
d. On XX/XX/XXXX due to XXXX ( XXXX XXXX  ) I was at XXXX XXXX XXXX doing XXXX tests that can be verified by medical records and doctor.

g. During this week, I also held client appointments in my office, XXXX XXXX, CA that can be verified through affidavits by me clients. 

Since I opened Chase Amazon in XX/XX/XXXX this card was replaced four ( 4 ) times due to fraudulent transactions. There is a failure at Chase to secure client information due to the amount of times someone was able to obtain my card information. I have never incurred any problems with individuals able to obtain my credit card information from other credit cards companies.
