Account closure

My account was frozen for suspected ***** activities and it had money in it. Despite me submitting all the necessary documents and information my account was and is still closed and my funds are still not returned and that was my salary account. Is it even legal to close an account with funds in it? On top of that my card was swallowed by the ATM and a pop up message was that the bank was instructed to take my bank card, how is that even legal? Soon after I submitted the documents I was told all things will be lifted but till now there has been nothing and no feedback was given unless I called and followed up on the case, the only thing I received was stories upon stories and nothing solid.
