I traded in our iPhone 11s months ago for new iPhone 15s and have been trying to get the trade in correctly applied on one of my lines since mid-October. I have called over 15 times and have gotten no help from the customer service team, other than to finally get shipping labels to send our iPhone 11s to Verizon. This has been the most frustrating and aggravating experience I’ve ever had in retail. Has anyone had similar trouble? If so, was it ever resolved?
