updating credit card information

Good Morning,

I have been emailed and asked to update my credit card information.  I went online to update it and the expiration date, credit card number and name was correct.  The only thing missing was the CSV number.  I added that, and saved it.  I am still getting an email asking for the update.  I'm not sure what to do at this point.  Can you help me? 

Thank you.
