Product: Checking or savings account

On XX/XX/XXXX I noticed a pending transaction on my XXXX XXXX  checking account number # XXXX in the amount of {$5000.00}, The transaction description as it appeared on my account transaction log as the following : XX/XX/XXXX ROBINHOOD DEBITS XXXX WEB ID : XXXX ACH debit {$5000.00} The above Transaction was posted to my account and no longer a pending transaction on XX/XX/XXXX The culprit behind the fraud and this compliant is Robinhood markets Llc or as known as Robinhood securities by the SEC. 
SEC ID : SEC CIK # XXXX. 
I will go in detail how I believe that the firm Robinhood itself is either a partner in this crime or its covering it up for some reason which is against the law. 

Even though I have a trading account with Robinhood I did not initiate or authorized the transaction, I contacted Robinhood on the early morning XXXX XXXX  PST XX/XX/XXXX and Robinhood confirmed that I had not initiated or authorized an ACH debit in the amount of {$5000.00}, They also confirmed that there are no incoming deposits in my account nor that the {$5000.00} was posted to my Robinhood account, They indicated that there were suspicious logins from a different state that I myself noticed and told them about, Since then on daily basis I have to go through their incompetent representatives over the phone and through email, They promised they assign and start the investigation, Through all the correspondences between me and them they intentionally change the subject and ignore the main issue which is WHY MY XXXX  ACCOUNT WAS DEBITED {$5000.00} WITHOUT MY CONSENT OR INTENT OR ACTION, They kept talking about how to keep my Robinhood account secure and kept taking about the Robinhood account itself. 
Even though I asked the question Why my account was debited they would not answer whether on the phone or through email, They have no explanation why they debited {$5000.00} and for what reason, At first they told me they suspected fraud, I kept on waiting patiently until today where they sent me an email about their investigation decision which is the following and a screenshot of this is included as an attachment here is today 's email main content : Good Morning, Thank you again for reaching out about potential fraudulent activity in your Robinhood account and your patience while we worked to complete our investigation.

Sincerely, XXXX Case ID : XXXX Right away I called them and asked them if there was no fraud how they explain the ACH debit that robinhood initiated a transfer of {$5000.00}, The Robinhood Rep was extremely rude and fighting with me and has no answer for the question he refused to let me speak to a supervisor and hang up on me, after this call Robinhood blocked me from contacting them through the only phone contact method which is request through the app and I can not call them any more I have filed a local police reprt which is attached, I have contacted the FEDERAL Bureau of Investigation XXXX unit but they don't give a receipt. 
Robinhood is obviousley covering this crime whether Robinhood itself committed the crime or not they are for sure covering it up and have no intention of what so ever of solving it and they have already ruled out from the last email I just quoted that no unauthorized activity had happened. 
I want to add some info, The bank account that in question was linked to my Robinhood account prior to the incident and I unlinked 3 days after the incident to prevent further fraud, I do not know if this ACH is a retaliation from Robinhood against me fro filing a complaint with the SEC 3 months ago, I do not know if they are covering a high profile customer of theirs that committed this crime, I don't know if Robinhood itself as a company committed this frau crime against me thinking they will get away with it. 
I am attaching my robinhood statement that shows my account Robinhood account number just in case Robinhood wants to claims falsely that the ACHwas deposited into my account which has not happened ( The XXXX screenshot shows the fraudulent ACH ). 
To summarize the whole thing is that Robinhood do not want to do anything to return my money, Do a through investigation or explain why my account was debited {$5000.00} and that they have no record for the transaction nor they know who did it ( Customer, Company insider, etc ), They do not want to discuss anything with me, They ruled out that no fraud has happened as shown in the attached email which is a lie and a cover up that can be easily Identified by XXXX bank, FBI financial crime unit, etc. 
I want the money to be returned to my since they themselves confirmed and still confirm that I did not authorize any ACH deposit in that amount.

Through the 14 email threads that I can attach piece by piece ( I attached only the first and that last wich was there decision ), They refuse to answer my questions, Their customer service are brushing me off, I am prohibited from contacting them via the phone
