First Niagara Bank Customer Service Issues

My name is Clint C. My situation is unique due to my ongoing divorce. I need help with accessing my bank statements from when I opened a checking account with First Niagara in [redacted], which is now with Key Bank. Unfortunately, I don't have my account number handy due to the divorce proceedings and Key Bank cannot provide me with the earlier statements. I would appreciate it if someone could compile my First Niagara monthly statements from [redacted] until the merger with Key Bank and email them to me as PDF files at [redacted] If digital copies are not possible, please send paper copies to: Clinton C. [redacted] Mapleton Rd. Sanborn, NY [redacted] Thank you for your assistance. Clint C.

My husband's sister, who resided in Pittsburgh, PA, experienced a health crisis and is currently hospitalized for rehabilitation or nursing care. As her power of attorney holder, we are trying to locate her checking account, potentially at First Niagara (or Key?). We possess an email containing a copy of a deposit slip from First Niagara, displaying her name and address. To confirm if this pertains to her checking account, we prefer to forward this email with the deposit slip photo for verification. Once verified, we would require contact details (including fax and phone) to submit the power of attorney, enabling my husband to manage her finances until she can resume. Our names are Harriet and Jerome Jansma, and the account belongs to Ida J. Masek (Ida Jane Jansma Masek) of [redacted] Carnegie St., Pittsburgh, PA.
