Checking or savings account: Managing an account

I opened a bank account with bank of america on the branch, they told me to open it online, I did and after the account was created I added some money to it, after I verified that the account was working I send a wire to myself from XXXX XXXX so that I can have enough money for a real state purchase I intended to do using that bank account. they subsequently decided to put a hold on my account initiated by the new account department, after some time they send a request to the wire department for investigation, not sure what about the wire was a problem and after more than a week they are holding my money with no timelines and no explanation on why are they doing it despite multiple attempts on asking for a reason or a clear timeline
