My experience: It takes at least 3-5 business days to get your credit when you return an item. I returned on Sunday, it's Wednesday-no credit to my account. Every other card I have I receive credit to my account immediately, or at the latest, the next business day. Oh! & don't use the message system because they give vaguest answers, which means they're either not reading your question completely, or they robo-answer.
