If your Cash App card has been stolen, it’s important to take immediate action in order to protect yourself from fraud. The first step is to cancel the card immediately. To do this, log into your Cash App account and click “Card Settings” under the “My Account” tab. Then select “Cancel Card” from the options displayed on the page. You will then be asked why you are canceling your card; select an appropriate reason and click “Continue Cancelation Process.” Once that process is completed, you can request a new Cash App card by visiting the official website or calling customer service at 1-888-255-1234 for assistance with replacing your original card with a new one. Additionally, if any fraudulent activity occurred while using your old Cash App card, you should contact Customer Support as soon as possible so they can investigate further and help you recover any lost funds due to unauthorized transactions.
