KeyBank William Flinn Hwy, Gibsonia

Absolutely the worst teller I've ever experienced. Just left the location on William Flynn 5 min ago. I've always seen this same lady in the drive through and she is the rudest and most non helpful person I've ever experienced at a bank. Fire this woman because you just lost my business and all of my friends and family. She basically just tried to accuse me of forging my own signature and won't let me deposit a check into my own account. Complete idiot, this is the same signature and check I deposit every week. I spoke to her supervisor and she just acted like she had no clue what was going on. How do you even keep customers coming back with customer service like this?? Seems like this place could use a clean sweep of employees....see ya key bank!!! And I'm going to make sure I post this everywhere to warn others not to use this bank.
