Unsatisfied with waiting period for investigation

I was not satisfied with the waiting period that takes for the bank's investigation committee or team regarding the fact that money is going out of my account and they can not stop any transactions from taking place in my account. A time waiting period of 14 days is not fine because by then my account would be with zero balance. The response that I should send an e-mail to address a complain was Unsatisfying because the at can mean more waiting time on my side
