How does one add a credit card to their account?

I tried to change my ticket from Will Call to Shipping and I get an error. 

Thanks
Lou

There were problems with the following fields:

• Credit card error Cannot complete transaction - no credit card on file.
  
• We're sorry, there was an error updating the shipping method.
  

Sounds like you should email customerservice@gencon.com.

You can change your credit card on file when you buy a badge or Event tickets. You cannot change it when you change from Will Call to USPS mailing.

So if he updates his file with a CC when he purchases his event tickets he would then be able to change it from Will Call to USPS?

Seems like you address only half the problem.

Thank you all. 

I will try to change my Badge shipping _after_ I purchase Event tickets. I'm think at that point a current credit card should be on file. 

Appreciate it,
Lou

I'm a DM. I'm not buying event tickets. I need my card account online now. Please fix this setup.
I have $10 credit from the previously paid shipping amount.. I'd be happy to use that. But you won't even let that kick in.
Fix this setup, please.
