DearCustomer- If the bank suspects any fraud may have occurred (I'm not saying it did) they can hold the funds and actually close the account by returning the funds to you. This is a sizable amount of money and it is possible that the bank will close your account depending on the results of any investigation they may be doing.
It is somewhat difficult to believe that no one at the bank will speak with you regarding this situation. Certainly there is a manager who can give you some details. You can file a suit against the bank if you wish but two weeks is not an unreasonable amount of time to hold funds, especially in this amount.
The general limit on holds is two weeks but if circumstances warrant something longer the bank is permitted to protect itself until they are certain all funds have been verified.
