Checking or savings account: Managing an account

I opened my US Bank checking account on XX/XX/23 using US Bank 's checking account bonus promo code ( XXXX ). The promotion stated that when you have made direct deposits totaling {$6000.00} or more within 90 days of opening the account, the account holder will receive a {$400.00} checking account bonus. I met the requirements by XX/XX/23, but as of XX/XX/23, I have not yet received the checking account bonus. I called the US Bank customer service representative today who said that she was unfamiliar with a checking account bonus and proceeded to transfer me to a closed department. This experience has left me feeling frustrated and concerned.
