TCF BANK $399.00 withdrawn from checking account Jan & March 2008 not authorized by my mother. I am joint owner on this this checking account Eastpointe Michigan

My mother, Mary, had funds withdrawn from her account at TCF bank without her prior knowledge or authorization!. $399.00 withdrawn from checking account 1/31 amd 3/31/2008. She contacted bank when she received her monthly statment due to the error. I have several letters and notes concerning her visit, my visit.,and my brother's visit to resolve this major rip-off! The branch manger, Mary Felczak, took the side of the company that withdrew the funds and would not take responsibility for her carlessness of matter brought to her attention back in Feb of 2008. Both times the amount of $399.00 was disputed but the same procedure was not followed. The end result was the same - a credit or a check for the amount of $798.00 was not processed. What a nightmare for my 85 year old mom!
Talk about high bank costs!! Did someone from the bank give out account information? My mom does not have computer or have credit card so how did this happen???
I have copies of all letters and cetified receipts with the latest day of June.
My mom just retired from 2 jobs in the last year or so and is on a fixed income. TCF owes her $798.00 along with (aggravation interest rate) from Jan 31 to date of check.

Sincerely,

Concerned Daughter
