If you signed up for a discount plan over the phone only to realize later that it was a scam, you'll need to act quickly. If you gave the scammer your credit card information, contact your bank immediately and report the fraud. Your bank will cancel your credit card and issue you a new one. They can also reverse any fraudulent charges the scammer has made.
If you gave the scammer your SSN, you'll want to place a fraud alert on your credit report or freeze your credit completely.
Act quickly to protect yourself from and recover from identity theft.
