The worst clueless bank😭

My Bank Zero account has been locked since [date]. I was told it’s because another bank reported it as suspicious. I have not been told which bank, nor what documents I need to provide. Every time I follow up, I’m told Bank Zero is still waiting for supporting documents from the reporting bank. In the meantime, I have no access to my account or funds. This is causing financial hardship, and I need Bank Zero to provide a clear timeline and resolve this, I swear I will further report them and close this account.
