XX/XX/XXXX I became aware that I received several checks regarding BOA class action lawsuits between XX/XX/XXXX - XX/XX/XXXX. I was n't aware of the checks being sent to me because during the time I was undergoing XXXX treatment for XXXX ( XXXX and XXXX ). I had no one to aid me with my day-to-day living during that time, which resulted my being incoherent of many matters beyond very basic needs for myself. 
I discovered the outdated checks XX/XX/XXXX/XX/XX/XXXX as I was packing to move back to Florida. I was horrified as began opening them and realizing that these checks were in my possession all this time - roughly XXXX envelops - give or take. 
I called the phone number that was listed in the letter attached to the checks, but it was a dead number. Bombarded with various emotions, from frustration to sadness, I began tearing up the checks and trying to rid them from my site. In the midst of this act, I regained my barrings and decided to hold on to what I had in order to try to retrieve the money that once I settled in Florida. 
XX/XX/XXXX I called Bank of America customer service regarding this matter. I was given a number to call about the settlement ( s ). I called it only to realize that it was the same dead number that I called before from the letters. Feeling deeply discouraged again, I discarded the remaining checks in hopes of being able to move forward and put this behind me. However, XX/XX/XXXX, I explained to one of my health care providers the situation and how I was still bothered by missing this money. She told me to not let this go because I genuinely have a good reason why I was n't aware that is documented. She gave me the phone number to the FDIC and a few other financial consumer agencies. She advised that if I am unable to obtain results through my own efforts that t I should retain attorney. 
When I called the FDIC, the representative advised me to appeal to BOA again providing them details of the info I shared above ( I provide extensive details upon my 1st contact ) before pursuing complaint or legal actions. Upon contacting BOA a 2nd time and providing them with more information about my situation, the rep gave me XXXX addresses to write to requesting that they provide accommodation due to XXXX. I mailed certified letters to the addresses that I was provided ( proof attached ). XXXX of them came back return to sender and the other was a letter telling me to write to the address that I mailed previously that came back to me " return to sender '' and the phone number that I had previously that was dead. 
At this point I called the FDIC back. The agent gave me the phone number to one of the administrators - XXXX XXXX - for one of the suits against BOA and the federal agency that regulates BOA. I called the XXXX, XXXX XXXX, who confirmed that there were XXXX checks that they sent me. The rep gave me an address a different address in XXXX MN to request accommodation reissuance due to XXXX. However, when I told him that there were more than XXXX checks I received, he said that he did n't know how what to tell me in how to hunt down other checks ... perhaps google it ... and that maybe " he 's told me too much already ... ''. He said that XXXX XXXX is a neutral firm only responsible for disbursing payments, however, that statement is questionable. I mailed certified letter to new address : Unclaimed Property Account, c/o XXXX Overdraft Unclaimed Property in XXXX MN, regarding the XXXX checks Rust Consulting confirmed I was sent.. However, I know that there were more than XXXX checks sent to me. As if today I have n't heard anything. I found a check from XXXX a couple of days ago ( attached ). 
To summarize - BOA is uncoorperative and are not straightforward about settlement. Please help me.
