Citibank — Checking and savings account

On 2/28/23 I deposited a check into my savings account I received from one of my tenants. On 3/1/23 at 0630 I was able to pay a bill and log on to my account. At 1000 my account had been restricted and all access to my account was blocked. I contacted customer service to inquire about my account and was told it was restricted due to the deposit of a stolen check. I told them it was not stolen. He stated that it needed further investigation and call back in 24 hours. I have called and spoken to numerous customer service representatives to be told that they need to verify the check by the maker but every time she calls they tell her that the phone number she’s calling from is not in her name. They have already taken the funds from her bank but state that the check is unverified. They sent me an email on 3/2/23 stating that they are closing my account and no debits or credits can come through but they accepted my direct deposit on 3/6/23. They now have everything locked in an account and will not give it back for 30-60 days.
