Product: Checking or savings account

I have 2 banks I bank with. 1. XXXX XXXX  2. US Bank I deposited a mobile check for {$1000.00} to XXXX XXXX  on XX/XX/XXXX, it sent me a message on XX/XX/XXXX after mobile deposit that it was rejected due to the date being incorrect. My client had accidentally put the date as XXXX. She corrected and initialed it, so I redeposited the same day and it rejected again. ( I have proof of this on my mobile banking app from XXXX XXXX. So, since it rejected twice at XXXX XXXX, I decided to go ahead and mobile deposit it at US Bank, which accepted it. However, Unbeknownst to me, on XX/XX/XXXX XXXX went ahead and accepted it, so they deposited it into my account. I of course had already also deposited it into US Bank on XX/XX/XXXX since XXXX showed they rejected it. 
US Bank, then debited it from my account since it cleared through XXXX XXXX. Which I am totally fine with. I had enough money in my account so it didn't go negative. I believe my balance AFTER the {$1000.00} deduction was at {$3900.00} in my business account. Which, I was closing since I know longer have that business. I had opened a personal checking and savings with US Bank, and was trying to transfer my business balance into my new checking via XXXX. Next thing I know, my account was frozen by US Bank and in the Fraud department on XX/XX/XXXX. That department which you can only reach through phone, would not give my any information and I was told there was no time frame on which they had to return my money or and that they also had the discretion to not return any! 
So, I went into the local branch and spoke to the Branch Manager, who was very helpful, I showed him All of my documents showing how XXXX XXXX  rejected my deposit twice, but then 2 days later accepted it. He emailed the fraud department asking for the hold to be removed on XX/XX/XXXX ( the same date I went in to see him ). He called me on XX/XX/XXXX, saying that unfortunately the fraud department rejected his request and they'd be closing out my account and sending me a check in a few days ( I saved this voicemail ), so then I emailed him on XX/XX/XXXX asking if he could please provide me with an ETA, he said he contacted them again via email, and they told him what they told me, they had no specified time on when and if they would return my money.

I then called US Bank fraud department on XX/XX/XXXX, and she researched it for me and said it's actually another department handling it ( she said the " closing department '' ), and she said their last notes on my account dated XX/XX/XXXX, said they were investigating it, there was no specified period on closing or returning my funds. The note also stated, that it would be returned by cashiers check through the mail IF there was any funds to send! I can't even reach that department that supposedly is researching my account to talk with them. That XXXX  also told me I would be receiving notice in the mail stating the same thing. I've yet to receive anything after more than 2 weeks. 
Yesterday, I received a notice in the mail about the {$1000.00} debit which I already was aware of, BUT in that same letter it stated they were looking into a deposit I made on XX/XX/XXXX in the amount of {>= $1,000,000}!!!! I of course have this notice for proof that US Bank is the one in error. They are the ones that did something on their end. So it appears they flagged MY account for that very large transaction. I've never ever had that kind of money in my life. Nor did I ever make a deposit in that amount! I am just trying to get back my {$3900.00} that I worked very hard to save. I've never bounced anything at US Bank and always had money in it. 
In addition, the personal checking and savings I had opened online had an initial opening deposit of {$100.00} in checking and {$75.00} in savings. They are denying me that {$170.00} as well. Again, I opened those personal accounts because I closed my business, and was going to transfer the business balance into my personal accounts I had just opened. 
Due me : {$3900.00} from my sole owner business account, {$100.00} from my new checking and {$75.00} from my new savings. 
Please help me. I have attached documents supporting my statement. 
Thanks, XXXX
