Q - OTA update not working AT&T sgh-i467 topic

I got the notification to upgrade my device OTA. I declined several times since i didnt have a reliable wi-fi connection. Now when i try to update , I get the message that my system is up to date. I tried to erase and reset my device but without luck. Can someone tell me how to get the update. Im currently ver 4.1.2 UCAMF2.
