An online order was marked "Delivered" but it was not. Contacted JCP "support" to have them re-send my missing items but they ignored my e-mails so I gave up. J.C. Penney lost a customer over a $34 order.
Contrast with Amazon, who replaced a missing order within a couple of days, no questions asked. I guess that's why Amazon is thriving. They know what "customer service" means.
