I experienced a similar fiasco trying to get a small amount (I can't remember how much ... maybe $5000) transferred. I changed the wire instruction, then changed it a second time which apparently froze the account. Fine, not a big deal, definitely my fault.
It took over a week of calls every day to get the damn account unlocked. I kept being told the person from security would call me -- guess what they never did. Finally a CSR took some initiative and verified my information and unlocked the account without going through the security moron. Why they couldn't do that day one I don't understand.
I want security, and I don't want someone stealing my money. But there must be a better way of verifying customer identity. In the time it took me to get the account unlocked they could easily have sent me a letter, or called me at my home phone to verify who I am.....
I think it's the same problem IB has elsewhere -- basically some of their employees are either lazy, incompetent or overworked -- I don't care which but either get them more help or get rid of them. Some of the employees are great -- I guess they just can't fire the sucky ones....
