I'm trying to change my payment method

I can't figure out how to change my payment. I had to cancel my credit card because it was hacked so I got a new one. I got an email from you, shown in below screenshot.

Please advise.

Based on the information I found when I checked the email address you are contacting us from, it seems that you have submitted a form that one of our users has created.

If you have questions regarding your submission, we can only suggest that you contact the owner of the form you have submitted. You can check the website where you submitted the form or the email you received after you made the submission to look for the form owner's contact details.
