TCF bank Requested overdraft protection to be removed in February. Magically the have no record. Wayzata Minnesota

Last February i added overdraft protection for one important transaction.  After going through i called their cs line twice in the following week regarding fair problems with the complicated situation, but definitely requested the overdraft protect be removed.  Ive had no problems, or reason to suspect that this hadn't been done until today, Nov 12, when i find I've been hit with $250 in charges.  As a "courtesy" they removed $74 like they were doing me a favour.  It's unacceptable and am closing my account due to Their incompetence.  They lost my business and didnt bat an eye.
