I know many people here have had problems getting their financial institution to honor stop payments, or to return money that is being held up after they requested the acct closed, and other situations. I came across a great forum last night at
bankersonline.com/ubbthreads/postlist.php/Cat/0/Board/consumer
In their forum they have an "Ask a Banker" question, where like in this forum even an unregistered guest can ask questions about banking procedures and policies.
