We are associated with the Martensart account that needs a new credit card number

Fred, who is in charge of this account is out of town and we can not get hold of him.  I need to know what level we usually have and what we need to do to get you credit card info to update the account.

I checked Martensart account and it is under Free plan user. Please login to your account and follow this guide: 

1. Click the User Icon found in the top of the page and click the Account text link.

2. Go to the Upgrade tab.

3. In the Payment section, click the Change Credit Card button.

Let us know if you need further assistance. Thank you.
