Complaint sub-issue: Transaction was not authorized

I have been a  US Ba nk costumer for more than 10 years. First checking account opened in   XXXX   XXXX  , and closed in   XXXX   XXXX  , by my request. During the years I would encounter unauthorized or unknown charges in the range of $  XXXX  {$150.00 } ( once or twice per year ). The dispute process would take 3-5 da ys or more to reverse these charges back to my account, though I would not face a hard time in proving they were false or security breached. Each time  US Ban k would apologize for any inconvenience, though they would repeatedly happen over and over. That 's why I closed it, and reopened a new account with the same  US Bank - big  mistake, should have switched to another bank. The first couple of years I did not see anymore strange or unauthorized activities, until   XXXX   XXXX  , and this time it wa s US Bank its elf aledging some ghost money I owed them, for which they were never able to prove documents or statements, other than what the system tells them, which is a very short phrase : " charged Off/PMT ''. In   XXXX   XXXX   XXXX    US Bank debits my c urrent savings account with them, in the amount of {$340.00}. I asked why?, and they stated I owed them from that checking account I had closed in    XXXX   . I had several phone conversations and in a branch in person, also requesting statements or some kind of document to prove that I owed the charges, but there was no prove. Within a couple days, continuing my determination, I say I was lucky to speak with a  US Bank  wise manager, and she could not explain or find statements either, and realized it was an unauthorized charge from the recove ry dept.,  and with friendly apologies she reversed the charge of {$340.00} back to my account with in 24 hou rs. Things kept going well, until   XXXX   XXXX   XXXX  .  US Bank de bits my checking account this time in much higher $ $ amounts, totaling {$770.00}, plus several overdraft charges of at le ast 4 or 5, becau se of their forced debits that deducted all the available $ $ amount from my checking account. I spent all day with phone conversations and stope d to two diff erent branches. The only answers I got from  one of them was only the w ord of mouth that I owe  US Bank all the se money, and the other was able to print me a statement from my closed account in   XXXX   and which makes it even more bizarre for their training or specialty as Bank customer service, is that the statement was declaring {$0.00} balance right in front of their eyes. Still, no one was able to give me a statement or letter, or any documents that showed I owed the amount of money that  US Bank  had charged me, and no one could reverse or dispute any of them. However,  Most of t hem were nice, I could understand they did not have control over their system, or did they? They also mentioned to me another charged off account which remains a ghost, since I did not have it! and they could not print me a statement or document to show the charges. What made it even more scary as of now by the end of the day, is that an agress ive manager from the  recovery dept. stated that : " you still owe more money to  US Bank starting  from {$99.00} and up '' for which he could not disclose the total, but said : " we will continue to debit your checking and savings account anytime we find a suporting balance, unauthorized and without notice just like we did it previously, and the charges would vary anywhere from {$100.00} to {$500.00}, as it seams fit t o US Bank. An d do not expect any statements or documents from us. We will only send you a leter to tell you how much you still owe us, but no details of what for, and no details on what we already charged you ''. At this point, I could hardly believe what I was listening to, it really seamed like  one of those scary scams that unlicensed and illegal businesses practice. Well, this came directly from US Bank  itself. Certainly I 'm overwhelmed, but because this is the first day for me which came as a shock, but it absolutely will go through a very detailed investigation, most likely through a law suit. No statements or No documents to prove the forced unauthorized charges is certainly in my favor. However, it will take sometime to take the money back, which so far is close to {$1000.00}, and could go even higher in days, if the fraud practices that the  US Bank representative stated are true. Or perhaps I may find another wise manager to reverse these forced charges back to my account. ( Highly doubt though, who knows ) I better take out some cash before US Bank steal it all. First thing in the morning! Than a legal investigation!
