Rick moved and changed his address with his credit card company, CItibank, but didn’t change it with the bank’s rewards program vendor. No problem: just put in a different shipping address when he placed the order, right? Not exactly. Now the company’s best option is for him to wait for the package to be sent to the address where he no longer lives, complain of non-delivery, and wait for a new package to come. This seems a bit inefficient.
