The only financial representative I have is the one at the bank. She opened my account for me and I always go to her when there is a problem or when I need to do something like transfer money to another account, open an addition account, etc.
It's actually nice to work with the same person every time because she's up to date on my accounts and needs. She handles issues very efficiently as well. Of course, I also work with the tellers to deposit or withdraw money but I don't really consider them financial representatives.
