Citibank Bank Account Or Service Complaint

Citibank Bank account or service department,

Savings account Account opening, closing, or management Illinois

I opened checking and saving accounts at Citibank on the phone. The rep said to expedite the matters to go to the branch, present ID, sign necessary forms and deposit the money. So I did. A week later it turned out they were missing a copy of my ID I presented in the branch. But they kept quiet until I called them on the phone asking about access to my money. Eventually they sent me an email with a form for ID copy so I had to fax the image of my ID with the form. After that they sent me an ATM card. But when I registered it I discovered that the access to the savings with the entire amount ( - ) of the deposit is blocked. Now they are stating that they do not have the signature card which is a lie. Without it the opening of the account would not have been complete and accepting the deposit would not be possible. Even written communication with customer service is infuriating. They completely ignore what is stated in the request and give absolutely irrelevant answer. At this point I worry about a very substantial amount of my money that they are holding and refusing access with made up reasons.
