Wells Fargo bank closed my accounts and haven't sent me my funds. I keep getting run around about who to call; what can I do?
If Wells Fargo suspect that you have been using the accounts for illegal activity, then they will block or close the accounts. They will not tell you why they have closed them, and they will not give you any money back until the investigations have concluded.
If that's the case, there is very little you can do about it.
Edit, in response to a lot of comments. Banks can be fined many millions of dollars if they are found to have allowed their accounts to be used for money laundering or other illegal activities.
So if a law inforcement agent tells the bank that a person is being investigated for such illegal activities, the bank has little choice as to what they will do. The account will be locked immediately, to stop the alleged criminal getting the money. The bank will not tell the customer what is happening, because you wouldn't tell an alleged criminal what they are being investigated for. The account holder will not be allowed access to the money, because it's subject to a criminal investigation.
There are two outcomes in the long term (which may be many months). Either the account holder is prosecuted and the money is seized. Or the account holder is given their money back and told to go away and never try to open an account with that bank ever again.
