Recently I have to make quite a few calls to banking and funds at IB. 1) email address change, 3 calls, 2) wire transfer setup instruction, 1 call, 3) actual wire transfer, 1 call, 4) mailing address change, have to call again. Every time I made change through the security device, and then have to call and wait on hold for a long time to verify that I made the change. I do appreciate good security measure, but that's what the security device is for. Shouldn't they trust it more? It's not like they are fond of customer services.
