Product: Credit card or prepaid card

In XX/XX/XXXX " courtesy checks '', routinely issued by XXXX XXXX ( although I requested on many occasions for them to be ceased ) were stolen from my mailbox and cashed by someone. 
I was informed of this nefarious activity by XXXX XXXX ' Fraud department ( the Bank where they were cashed ), receiving a call on the Monday following the Thursday they were cashed and was informed 3 checks totaling {$6000.00} had fraudulently were signed with my signature and had been cashed by one XXXX XXXX ( who XXXX XXXX had on security camera ). I related to XXXX XXXX I knew no XXXX XXXX and the checks had to have been stolen from my mail box or otherwise she had no way of obtaining them. 

I immediately contacted XXXX, who bounced from XXXX, XXXX, XXXX, or some location in between disconnecting me on several occasions throughout that day. 

The following day I finally spoke to someone in the fraud department and explained what was going on and they blocked the account and assured me all was well and not to make payments on the {$6000.00} charges ( since my account was otherwise at a zero balance. 

I was issued a new card ( which I never received ) and upon letting them know that, still another another card was issued. At the time of the fraud, I told XXXX, once again, to NEVER send our another " courtesy check '' on any of my three open credit card accounts and they told me it would take thirty days to end that practice. I spoke to our local law enforcement who said they really do not go after the felons in these cases. 

As this saga continues, in XX/XX/XXXX, I received another form letter from XXXX indicating there had been suspected fraudulent activity on the new card. My belief was although, I had been assured the XX/XX/XXXX investigation had been completed and resolved, XXXX transferred all those fraudulent charges to the new card they had issued - I also receive a letter stating that I had not paid them in 100 days and my account was in collections. I am XXXX XXXX XXXX with excellent credit and have missed one payment in my life. Their ineptitude in handling this manner has caused my FICO score to drop more than 100 points due to a ( seriously delinquent account ). I have made numerous calls to XXXX in the past two weeks that have mostly been handled by their overseas call centers who have a standard manual ( as does their stateside operations ) and no one really has any authority to do anything but bounce me from one associate to another. In fact, when I told someone today about the complaint I was filing, they had no name, just : Office of the President XXXX XXXX XXXX XXXX DE XXXX I was assured today the " courtesy checks '' would cease ( within 30 days, which is what I was promised in XX/XX/XXXX when this was supposedly resolved at that point. I am hoping you can help me clear this matter up and possibly refer me to counsel or let me know if any class action litigation is pending concerning XXXX. If any litigation is pending I will very willingly ( although it is against my nature ) become a plaintiff. 

Not only is XXXX inept, but I feel fraudulent in how they handle the distribution of these unsolicited mailings that can be easily stolen and reproduced. I may help to be a voice for the thousands of Americans who are victims of these underhanded practices at the hands of banks with whom they receive credit cards ( by the way, I contacted XXXX in XX/XX/XXXX and have not received another " courtesy check '' which leads me to believe incompetence at XXXX and an almost non existent communications chain that makes it nearly impossible to speak with anyone with authority. Any help you can give me in this matter would be appreciated.
