Poor Customer service

This has got to be the worst bank in the world. Having merely transferred funds between 2 accounts in my name inside Citibank, my account has been locked since 27th July 2020, with no access to funds or the power to send them a secure message. I had 2 phone conversations with them, I sent 2 emails to their security team, and that I additionally wrote to them, however still no access, that is sixty days now! I've registered a proper criticism with the monetary investigator, sadly, they do not seem to have abundant use either. Once I purchase it back to my account, funds are going to be transferred to Mr. Smith, World Health Organization I even have to mention area unit a much better bank. Having withdrawn most of its operations from the United Kingdom, I cannot see Citibank continuing to trade with such poor client service.
