Troubleshooting payment issues

In case your card is being declined - it can be due to one of the following reasons:

  • A typo in the card number. Try entering your card number again.
  • An expired credit card. If your card hasn’t expired, check to make sure the date was entered right.
  • A typo in the Card Verification Code (CVC). 
  • Mismatched billing address with the one on file with your bank. 
  • Your credit limit was reached. Contact your card provider for more information.

If you tried all these and still couldn’t get your card to work, contact your card provider.
