No access to my own money

My account has been frozen for the past two days and the only thing I should do to resolve is wait for their call. This is the worst nonsense I have ever experienced. Now I cannot do anything pretty much because they are conducting an investigation but have not contacted me once to find out anything from me about my account. I have gone into a branch and contacted the contact center multiple times with no progress, the only thing they can help me with is to tell me to wait.
