I have a Barclays Arrival card and recently purchased some show tickets from MGM Grand. I ended up calling MGM 2 days ago and asked for a refund (found the tickets cheaper elsewhere), and they said the refund would be processed in 7-10 business days. However, I recently got a new Arrival card in the mail with a different card number and activated it online. Will my refund still go through even though they have my old card number on file? Thanks.

Let me know if this question is in the wrong thread/forum and I'll move it. Thanks.
