If you’re getting an error message, check the following requirements: The credit card number, name on the card , and CVV you’ve entered is a Visa/MasterCard/Amex or Visa Debit. The laptop, smartphone, etc. you’re using has a Canadian IP address. If all of the above is correct and you’re still getting an error message, connect with the bank that issued your credit card to check that the address and postal code associated with your card are correct.
