As long as you do have a current MasterCard, go online or call their 800 number (on back of card) to ascertain whether they really charged anything. If so, dispute it. If not, just ignore it and delete the email.
I keep getting emails about charges or payments to my American Express card. I do not have, nor have I ever had one of their cards, so just delete as “junk” and ignore them.
It’s a phishing scam email. Just report it as spam and delete it. One of my email addys gets dozens of these everyday, since my hubby used that email to register for something. :rolleyes:
