The Best Way to File for Citibank Complaints

Citibank is one of the largest financial institutions globally and boasts of serving over 35 million customers in the United States alone. A huge client base like this can come with its fair share of woes. The most common include credit card issues such as deactivations and declines. The second complaint typically touches on account fraud where fraudsters hack Citi customer accounts and withdraw the money to fund purchases.

Bank scams are also major complaints where their customers are duped into giving out their account information, leading to fraud and huge financial losses.

If you are dealing with any of the issues mentioned above and you would like a faster and easier process to make a complaint, try DoNotPay. We not only help you with the complaints but also file a lawsuit on your behalf if the response you receive is not satisfactory.
