Fraudulent charges refer to unauthorized or false transactions made on a credit card, debit card or bank account. These types of charges can occur when someone steals your personal information and uses it to make purchases or withdraw money from an ATM without your knowledge or consent. Fraudulent charges can also result from stolen credit cards or debit cards being used for transactions, or from merchants processing fraudulent transactions. If you suspect that there are fraudulent charges on your account, it is important to notify your bank or credit card company immediately so they can investigate and take appropriate action.
