XX/XX/XXXX : Attended appointment with Bank Manager at local ( to XXXX XXXX ) Branch of Bank of America, to discuss case.

XX/XX/XXXX ; Received Letter from Bank of America, referencing ( original ) Claim # : XXXX, with a page of something purported to be documentation used in their investigation. The image is of such low quality, that it is not at all clear what this documentation refers to.
