We always respond to emails, but there are providers who will not accept email from us. Nothing we can do about that.
There are two reasons you will not get a response.
1) We never got the email to begin with. Our spam filter could eat it because it has things attached to it that should not be there (happens a lot with email containing HTML).
2) Your ISP is not accepting email from us.
You can check the following link for the ISP's we know who instantly reject email from us.

As to your immediate situation. If you have not updated the card information for over 2 years, then I would be willing to bet the expiration date has come and gone and that is why it is getting rejected.
If emails are not getting through, then PM me your email address and I can check into that and/or call Carrie (817-431-8840).
