How to speak to a human

Hello, good day and thanks for your question. Sorry to know about this and I understand that you have encountered an issue with regards to the payment for your subscription.

If your card is up to date and you have also verified that it is working for other purchase that you made online, please check and try this on a different browser or by using inPrivate or Incognito browsing and another alternative is to link your card to PayPal and use it as payment method. Please see below for other things that you can also check with regards to this issue.

• Enter your name precisely as it appears on the card and only include your middle initial if it appears on your card.
• If this is a company card, enter the company name as both a first name and last name. For example, if the company name is "My Company" you may split the company name into the first and last name fields.
• If the company only has one name, for example, "Company," enter the company name in both the first and last name fields.
• If you are asked to enter the address and it exceeds the Address 1 field, use the Address 2 field and do not shorten or abbreviate your address.
• The card number and type cannot be edited, so if you make a mistake, you'll need to add a new one with the correct information. Other credit card information can be edited, such as billing address and expiration date.
