I never provided bank info during chapter 11 voting process but, i provided my ballot to the brokerage firm(the nominee).Do you have a brokerage account with the same bank where you originally purchased Washington Mutual, Inc. related instruments?.Let me know if you have any general questions. I am just somebody in a different situation.Contact the institutions by email,just like what you did on a public forum and demand answers.I think they have to respond.Take care.
