I'm unable to enter my new credit card, so my buyer can get his refund. I've been trying for two weeks and no one will answer the phone. I get emails and invoices. From stub hub asking for the new card info. but I get no help.
So sorry for the trouble. If you're having issues with card, you can send a private message to any one of the moderators here. But if the card number is required, you will need to call 866-788-2482. @johnwalldow
