I signed up for Chase Sapphire and got approved. I read somewhere that it's best to apply for another card the same day. So applied for Chase united explorer right after and got the 'You are approved' message and email. I got the Chase Sapphire card in the mail but not the United Explorer card. After waiting for a few days called up to find out when I would receive my card and was told that they closed the card. This is after the approval and email saying my card is on the way. I'm so disappointed. Anyway to appeal it? CS said there is nothing they can do.
