KeyBank NA Bank Account Or Service Complaint

KeyBank NA Bank account or service department,

Checking account Account opening, closing, or management New York

I lost - blank checks ( in my checkbook ) it was not stolen, but misplaced. I asked to have my checks stopped. there should not have been any fee on stopping a lost blank check, but I was charged for it. And in attempting to rectify the situation, service representative tried to put a hold on my account and close the account out, stating that it was policy to do so. It was averted, because I refused to give out my SS #, and problem was fixed finally by another rep in the supervisory role 2 hours later. However I wish to file a complaint for the service rep who deliberately mis-informed the customer and attempted retaliatory action in attempting to close the account when it was not needed.
