Unbelievable bad service

My bank account was frozen again because according to the bank I did not provide the necessary documents.<br> <br> I have my account from 7 years from now and I provided my documents at least 5 times. Every time I'm told I don't have to worry about it again and every time I have the same problem because my documents get lost by the bank employee. <br> <br> I did several transactions and I even opened a fixed investment account, how can it be possible if I never provided my documents?<br> <br> Their explanation were unclear and ridiculous. They did not want to provide me with a written declaration of the situation. <br> <br> They're playing with people money and people life and they're incapable of taking responsibilities for their own actions.
