Product: Checking or savings account

I had my checking account at Fifth Third Bank for years. I started it when I lived in XXXX, XXXX probably like 10 years ago. I moved to XXXX & wanted to keep my bank but since I had moved states I had to open a new checking account in XXXX XXXX. That was fine & eventually I ended up opening a savings account through them as well. The entire time I had my account I believe that I was a good customer. I may have had some bounced checks, nothing intentionally & always paid them if so & kept my account in the positive. I used my checking account for everything. Throughout the years of having my account I was also working on fixing & building my credit. I have never, ever been accused of fraud or anything along those lines & I would never do it. So for my bank to treat me so badly with this one thing supposedly happening just blows me away. Honestly me being a customer of theirs, a good customer, I feel that they should've helped me & and told me their thoughts which were I was getting scammed. Instead of them helping their customer that knows absolutely nothing about scams they chose to treat me like I was nothing and now have ruined all the hard work I have done for myself to better my life. 
I had my resume on all the job boards trying to find full time employment. I really needed remote work due to not having a vehicle at the time. A guy named XXXX XXXX got ahold of me via email. He told me that he found my resume on one of the job boards & was interested in me being his assistant. I would be like his second hand, the pay was great, id be able to work remotely, he was going to train me on everything I needed to know. He thought I'd be good because I'm a XXXX, I am excellent at customer service plus I had owned my own business before. He knew this from my resume. Everything he said sounded good. Now know this..I know nothing about doing scams or getting scammed. I have never been involved in anything like that, I do not know anything about any of it. So I thought he was legit. So I agree to work for him. He gives me a check for something like XXXX. Says I need to deposit it so that I can pay the guy who was going to come work on my computer, a guy was going to come set my computer up with all the programs and such that I would need to work. Actually XXXX was supposed to be having a new computer sent to me & then somebody would come set it up. He said I needed to deposit the check so that I could pay the guy when he came & whatever money was left after paying him I would use to buy all the supplies and such that id need. So that's what I thought was going on. I deposited the check, the bank locked my account, the check was never even put through, funds never touched my account. I had to call the bank to see what was going on, why I couldn't get into my account. They were completely rude & would not tell me much of anything except the check was under investigation and they were closing my account. Nobody would really tell me anything. Now since this is not typical of me & they knew that it would've been nice if they wouldve explained to me what was going on and that I was probably getting scammed since they knew. Instead they treated me like complete XXXX XXXX  like I was nothing and guess what I did get scammed! Why? Because I didn't know anything! And my bank who's suppose to help people recognize scams chose to XXXX on me instead of educating me. Then they have the nerve to report me as fraud to where now I can't open up another bank account anywhere or get credit cards & who knows what else. I don't even want an account with a bank like them but I do want that tool off my record. It's not right and they do not even know if that check was bad or not because they never put it through. I want the comment or whatever false things they have said about me off my record please. Thank you
