Product: Checking or savings account

On XX/XX/2023 I went into the Chase bank to deposit a check in the amount of {$7800.00} into my checking account after logging in and realizing I wasnt able to do a mobile deposit. When I arrived at the bank I filled out my deposit slip to deposit the check into my checking. The bank teller altered my deposit slip and deposited the funds into my savings account without telling me. Once I realized he had deposited it incorrectly I went back in and he said Im sorry I should have told you, your checking account was closed. He gets on the phone trying to find out why. He gets the run around from every person he called. He gave up after 30 minutes saying we would have to call ourselves. 
I called chase bank customer service and was told a ton of lies for about 45 minutes. The guy said it was closed due to a {$500.00} claim and another claim for XXXX he then comes back and says that was incorrect however he cant get a hold of the department he needs because its closed and to call back tomorrow. I call back first thing XX/XX/2023. After being transferred multiple times and dealing with an extremely rude representative, she tells me my account was closed due to a fraudulent transfer made to my account for XXXX cents. After being told several times theres nothing she can do and that the funds in the account will be consolidated and then whats left will be mailed out. 
I asked to escalate the matter and talk to a manager. I remained on hold for an entire hour. While on hold I went to do some investigating. I found that there was a transfer initiated of XXXX cents however it was a transfer initiated by Chase and the XXXX cents came from my OWN savings account. They regularly transfer money from savings to checking if checking doesnt have enough to cover a charge. I look online and find a letter they sent on XX/XX/2023 stating that they had initiated the transfer. Once she comes back, she says that the manager approved reopening my checking account and that it will take one business day to reopen and funds available. I then proceed to ask when my check of {$7800.00} will be made available. They put a 7 day hold on this check and refuse to give me any part of it. This is a second payment from this client so clearing this check shouldnt be a problem. She says since this is the first check Ive ever deposited into this savings account theres nothing she can do. I explain that the teller put it in the wrong account and she continued to argue and refused to help. She then said I did what I was supposed to do thank XXXX then hung up on me. It is now XX/XX/2023 and my checking account still doesnt work and my check is still on hold. Its been 3 days now that I havent been able to run my business because I dont have access to my funds. This isnt the only issue I have had with chase holding funds and not making even the {$220.00} required readily available. We trust these financial institutions to have our backs, we are their clients after all right? However anytime I need to call for help I get the run around. The biggest one is that chase can not verify funds on checks deposited. They take the full 7 days to release funds just ensuring they stay within legal limits while their customers suffer.
