*****ulent Withdrawals FNB/RMB

I am appalled at the lack of service provided in resolving *****ulent withdrawals from 6 of our accounts by FNB/RMB from mid-October to date. My 2 Private Bankers input yesterday was that I investigate some of the *****ulent transactions myself. I was told today to phone the ***** Department myself. One never answers the phone during the day, but consistently phones me while driving home and states that they cannot assist as they do not have the documentations while driving. What is the point of having Private Bankers for all my accounts?
