Complaint Against Well Fargo Bank Situation Details : Well Fargo Banking Error that I am paying for currently. 

I received a check from XXXX XXXX Administrators for a car accident I was in on XX/XX/XXXX. I was going to deposit this check online, so I wrote on the back, deposit online only but the funds of {$8100.00} was too much to deposit online. So, I put a line through the check on the 2nd line of the check below my signature. Although this check had been scratched on the 2nd line the Well Fargo teller continued to process the check when I went in to make the deposit to my account. Both the teller and her supervisor saw the check and made no comment about the scratched-out information on the back. If they had and told me, they could not deposit the check due to the scratched-out writing ( That I wrote on the 2nd line ) I would have gotten a new check from XXXX XXXX Administrators with no issue. Now I understand Wells Fargos end on a check being altered might cause a flag but that should have been caught at the branch or by the Fraud department before they allowed the funds to be validated. Then have be me go and get a new check to be deposited to the account. Now they are stating that there is suspicious activity on my account due the check and they closed my account. Even though I have been getting direct deposits for months. There was a negative balance at the time of deposit transaction, that would have Been cleared by my check I was depositing and 2. Would have been cleared by my direct deposit that was coming out just a few days after the check was deposited, but before that happened Wells Closed my account. They did inform that there could be a 7 day hold to validate funds of a large amount which I was okay with, then they said 2 weeks which would then they said on XXXX the funds would be available. 

Now they are continuing to hold my funds asking for something called Proof of issuance making me validate the check by getting something written to say this check is a check made out to me. I have provided them with as much information as I can get from XXXX XXXX Administrators group, phone numbers contact names, etc. but they still are making me chase down validation information. Which isnt right because they deposited the check which verified the funds and used it on my account. So how can they use it to clear a negative balance but then keep the rest? I have been able to get some of the money out, but there is still a balance of {$3200.00} that they are holding from me. That is the amount I am looking to get off hold of Wells Fargo. I have bank statements, email conversations with XXXX risk that are associated with the email account assigned to my former Wells Fargo account. I will attach these documents to the claim. This also shows how Wells paid my negative balance with the deposited check showing there used and verified the funds. I also have a document from XXXX XXXX showing wells did clear the funds on their side on XX/XX/XXXX. 

The mistakes this to make it seem like was at fault and like I was doing criminal activity even though the mistakes that have been made are solely on Wells Fargos side. 
I have contacted both Berkly Risk Administrators and Wells Fargo Fraud department that I would like CFPB to contact and mediate if possible so I can put this failed mess of Wells Fargo behind me. 
Been trying to work with Wells on contacting XXXX but keep give me different responses. They also never said why they actually closed my account.
