I have never had any problems either.
In matter of fact their security services are top notch.
A couple months ago I tried to deposit a very large check using the ATM deposit.The next morning it was gone! So in a panic I rushed the the branch I made the deposit at,and was told there was a problem on my signature,and I would be receiving my check back by mail within 7 days.
Angry as I was,I knew at least they are on top of things,I guess
When the check arrived back,I took it and deposited it in my First Tennessee account the same way,with no problems.Now that makes me wonder how FT's security is....
