JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Identity theft / Fraud / Embezzlement Illinois

I believe my credit card was used fraudulently. I do n't understand how the card was used since it did not leave the cardholder 's possession. The card company did not provide copies of every charge. Dates and times of many charges could not have been made by the card holder. - or more copies of receipts clearly show a signature that is not of the card holder. I believe the pattern of charges are consistent with obvious fraud. At no time did the card company contact me and question or ask about the charges. The charges exceeded the indicated credit limit and the card company allowed them anyway by just raising the limit. No explanation as to why the charges valid have been given. The card company response is just ... determined that the transactions were valid ''. There has been no response with any substance to my letters or questions.
