KeyBank

The teller at this branch vocalized my transaction, a deposit into my business checking account so loudly the rest of the customers in the bank could hear it quite clearly. And the second teller I spoke to the next day, upon my return to complain, told me my balance out loud instead of writing it on the back of a deposit slip or other piece of paper, which is the proper and secure way of conveying personal banking information while at the window. Luckily there was no one else in the bank at the time. I complained to the acting manager that day and left my contact information. I have not received a return call from the branch manager to date.
